Effects unit

Effects units are cyberbanking accessories that adapt how a agreeable apparatus or added audio antecedent sounds. Some furnishings cautiously "color" a sound, while others transform it dramatically. Furnishings are acclimated during reside performances or in the studio, about with electric guitar, keyboard and bass. While a lot of frequently acclimated with electric or cyberbanking instruments, furnishings can aswell be acclimated with acoustic instruments, drums and vocals.12 Examples of accepted furnishings units cover wah-wah pedals, fuzzboxes and reverb units.3

Effects are housed in amplifiers, table top units, "stompboxes" and "rackmounts", or they are congenital into the instruments themselves. A stompbox (or "pedal") is a baby metal or artificial box placed on the attic in foreground of the artist and affiliated to his or her instrument. The box is about controlled by one or added foot-pedal on-off switches and contains alone one or two effects. A rackmount is army on a accepted 19-inch accessories arbor and usually contains several altered types of effects.4

While there is currently no accord on how to assort effects, the afterward are seven accepted classifications: distortion, dynamics, filter, modulation, pitch/frequency, time-based and feedback/sustain.56 Rock guitarists acquire their signature complete or "tone" from their best of apparatus and effects.7

Formats (form factor)

Effects units are accessible in a array of formats or "form factors". A musician's best of anatomy agency is about bent by the apparatus he or she plays, the agreeable bearings (recording or reside performance) and what he or she can afford. Stompbox appearance pedals are usually the smallest, atomic big-ticket and a lot of asperous blazon of effect. Rackmount accessories are almost big-ticket and action a added ambit of functions.8 An furnishings assemblage can abide of analog or agenda circuitry. During a reside performance, the aftereffect is acquainted into the electrical "signal" aisle of the instrument. In the studio, the apparatus or added sound-source's abetting achievement is patched into the effect.910 Anatomy factors are allotment of a flat or musician's outboard gear.11

edit Stompboxes

Stompboxes, or furnishings pedals, are furnishings units advised to sit on the attic or a pedalboard and be angry on and off with the user's feet. They about abode a individual effect. The simplest stompbox pedals accept a individual footswitch; one to three potentiometers for authoritative the effect, accretion or tone; and a individual LED affectation to announce whether the aftereffect is on. The a lot of circuitous stompbox pedals accept assorted footswitches, eight to ten knobs, added switches, and an alphanumeric affectation awning that indicates the cachet of the aftereffect with abbreviate acronyms (e.g. DIST for "distortion").812

An "effects chain" or "signal chain" may be formed by abutting two or added stompboxes. Aftereffect chains are about created amid a preamplifier (“preamp”) and the guitar amplifier. When a pedal is off or inactive, the electric audio arresting advancing in to the pedal is absent assimilate a "bypass", consistent in a "dry" arresting which continues on to added furnishings down the chain. In this way, the furnishings aural a alternation can be accumulated in a array of means after accepting to reconnect boxes during a performance.13 A "controller" or "effects administration system" allows for assorted aftereffect chains to be created, so that one or several chains can be affianced or able by borer a individual switch. The switches are usually organized in a row or a simple grid.14

To bottle the accuracy of the tone, it is a lot of accepted to put compression, wah and overdrive pedals at the alpha of the chain; accentuation (chorus, flanger, appearance shifter) in the middle; and time-based units (delay/echo, reverb) at the end. When application abounding effects, exceptionable babble and hum can be alien into the sound. Some performers use a babble aboideau pedal at the end of a alternation to abate exceptionable babble and hum alien by overdrive units or best gear.15

Rackmounted effects

edit Rackmounts

Rackmounted furnishings are congenital into a case advised to accommodate into a 19-inch arbor accepted to the telecommunication and accretion industries. A rackmount assemblage may accommodate cyberbanking chip identical to a stompbox's, although its circuits are about added complex. Unlike stompboxes, rackmounts usually accept several altered types of effects.16

Rackmounts are a lot of frequently acclimated in recording studios and "front of house" reside complete bond situations, admitting abounding musicians use them in lieu of stompboxes. Rackmounts are controlled by knobs or switches on their foreground panel, and generally by a MIDI agenda ascendancy interface. During reside performances, a artist can accomplish rackmounted furnishings application a "foot controller".17

"Shock mount" racks are advised for musicians who are shipment accessory on above tours. Accessories that are beneath than 19 inches advanced may use appropriate "ear" adapters that acquiesce them to be army on a rack.18

edit Congenital units

Effects are generally congenital into amplifiers and even some types of instruments. Electric guitar amplifiers about accept congenital reverb and distortion, while acoustic guitar and keyboard amplifiers tend to alone accept congenital reverb. Since the 2000s, guitar amplifiers began accepting congenital multi-effects units or agenda clay effects. Bass amplifiers are beneath acceptable to accept congenital effects, although some may accept a compressor/limiter or distortion.19 Instruments with congenital furnishings cover Hammond organs, cyberbanking organs, cyberbanking pianos and agenda synthesizers.20 Occasionally, acoustic-electric and electric guitars will accept congenital effects.2122

edit Multi-effects and tabletop units

A multi-effects accessory (also alleged a "multi-FX" device) is a individual electronics furnishings pedal or rackmount accessory that contains abounding altered cyberbanking effects. Multi-FX accessories acquiesce users to "preset" combinations of altered effects, acceptance musicians quick on-stage admission to altered furnishings combinations.23

A tabletop assemblage is a blazon of multi-effects accessory that sits on a board and is controlled manually. One such archetype is the Pod guitar amplifier modeler. Agenda furnishings advised for DJs are generally awash in tabletop models, so that the units can be placed alongside a mixer, turntables and CD abrading gear.24

History

Studio furnishings and aboriginal angle abandoned units

The ancient complete furnishings were carefully flat productions. In the mid to backward 1940s, recording engineers and beginning musicians such as Les Paul began manipulating reel-to-reel recording bandage to actualize answer furnishings and unusual, affected sounds. Microphone adjustment (“miking”) techniques were acclimated in spaces with distinctively advised acoustic backdrop to simulate answer chambers.252627

In 1948 DeArmond appear the Trem-Trol, the aboriginal commercially accessible stand-alone furnishings unit. This accessory produced a tremolo by casual an instrument's electrical arresting through a water-based electrolytic fluid.28 Most stand-alone furnishings of the 1950s and aboriginal 60s such as the Gibson GA-VI vibrato assemblage and the Fender reverb box, were big-ticket and impractical, acute beefy transformers and top voltages. The aboriginal stand-alone units were not abnormally in-demand as abounding furnishings came congenital into amplifiers. The aboriginal accepted stand-alone was the 1958 Watkins Copicat, a almost carriageable bandage answer aftereffect fabricated acclaimed by the British band, The Shadows.2930

Amplifiers

Amplifier built-ins were the aboriginal furnishings to be acclimated consistently alfresco the flat by guitar players. From the backward 1940s onward, the Gibson Guitar Corp. began including vibrato circuits in admixture amplifiers. The 1950 Ray Butts EchoSonic amp was the aboriginal to affection the "slapback” answer sound, which bound became accepted with guitarists such as Chet Atkins, Carl Perkins, Scotty Moore, Luther Perkins, and Roy Orbison. By the 1950s, tremolo, vibrato and reverb were accessible as congenital furnishings on abounding guitar amplifiers. Both Premier and Gibson congenital tube-powered amps with bounce reverb. Fender began accomplishment the tremolo amps Tremolux in 1955 and Vibrolux in 1956.31

Distortion was not an aftereffect originally advised by amplifier manufacturers, but could generally calmly be accomplished by “overdriving” the ability accumulation in aboriginal tube amplifiers. In the 1950s, guitarists such as Willie Johnson of Howlin' Wolf, Paul Burlison of Johnny Burnette & The Bedrock N Roll Trio and Link Wray advisedly added accretion above its advised levels to accomplish "warm" adulterated sounds.32 Wray's seminal 1958 recording "Rumble" aggressive adolescent musicians such as Pete Townshend of The Who, Jimmy Page of Led Zeppelin, Dave Davies of The Kinks, and Neil Adolescent to analyze distortion. Davies would abundantly doctor the speakers of his amp by slitting them with a razor brand to accomplish an even grittier guitar complete on the 1964 song "You Really Got Me".33 In 1966, the British aggregation Marshall Amplification began bearing the Marshall 1963, a guitar amplifier able of bearing the adulterated "crunch" that bedrock musicians were starting to covet.3435

J Mascis of the American bedrock bandage Dinosaur Jr. helped to re-popularize analog stompboxes in the 1990s.36

Stompboxes

The cyberbanking transistor assuredly fabricated it accessible to charge the aural adroitness of the recording flat into small, awful carriageable stompbox units. Transistors replaced exhaustion tubes, acceptance for abundant added bunched formats and greater stability. The aboriginal transistorized guitar aftereffect was the 1962 Maestro Fuzz Tone pedal, which became a awareness afterwards its use in the 1965 Rolling Stones hit “(I Can't Get No) Satisfaction”.3738

Warwick Electronics bogus the aboriginal wah-wah pedal, The Clyde McCoy, in 1967 and that aforementioned year Roger Mayer issued the aboriginal octave effect, the Octavia.3940 In 1968, Univox began business its Uni-Vibe pedal, an aftereffect advised by acclaimed audio architect Fumio Mieda that mimicked the odd appearance about-face and choir furnishings of the Leslie alternating speakers acclimated in Hammond organs. The pedals anon became admired furnishings of guitarists Jimi Hendrix and Robin Trower. Upon aboriginal audition the Octavia, Hendrix allegedly rushed aback to the flat and anon acclimated it to almanac the guitar solos on "Purple Haze" and "Fire"41 By the mid-1970s a array of solid-state furnishings pedals including flangers, choir pedals, ring modulators and appearance shifters were available.4243

In the 1980s, digitized rackmount units began replacing stompboxes as the furnishings architecture of choice. Generally musicians would almanac "dry", changeless advance in the flat and furnishings would be added in post-production. The success of Nirvana's 1991 anthology Nevermind helped to re-ignite absorption in stompboxes. Throughout the 1990s, musicians committed to a "lo-fi" aesthic such as J Mascis of Dinosaur Jr., Stephen Malkmus of Pavement and Robert Pollard of Guided by Voices connected to use non-digital (analog) furnishings pedals.44

"Clipping" an instrument's audio arresting produces distortion

Distortion furnishings actualize "warm", "gritty" and "fuzzy" sounds by "clipping" an instrument's audio signal, which distorts the appearance of its beachcomber anatomy and adds overtones. Baloney furnishings are sometimes alleged “gain” effects, as adulterated guitar sounds were aboriginal accomplished by accretion the electric ability accumulation (i.e. gain) to tube amplifiers.454647

Distortion and overdrive: Baloney and overdrive units re-shape or "clip" an audio signal's beachcomber anatomy so that it has bedfast peaks, creating "warm" sounds by abacus accord or "gritty" sounds by abacus cacophonic overtones. In tube amplifiers, baloney is created by burden the instrument's out-going electrical arresting in exhaustion tubes or "valves".4647 Baloney furnishings adapt from overdrive furnishings in that they aftermath almost the aforementioned bulk of baloney at any volume. Overdrive units, abundant like tube amps, aftermath “clean” sounds at quieter volumes and adulterated sounds at louder volumes.4849

Distortion and overdrive effects: Boss DS-1 Distortion, Ibanez Tube Screamer, Marshall ShredMaster, MXR Baloney +, Pro Co RAT.

Fuzz: A down pedal or “fuzzbox” is a blazon of overdrive pedal that clips a sound-wave until it is about a squarewave, consistent in a heavily adulterated or "fuzzy" sound.4750 Fuzzboxes aswell accommodate abundance multiplier chip to accomplish an even harsher accentuation by abacus circuitous harmonics.5152 The Rolling Stones’ "(I Can't Get No) Satisfaction" abundantly affected the use of down effects.26

Fuzz effects: Arbiter Down Face, Electro-Harmonix Big Muff, Shin-ei Companion FY-2, Univox Super-Fuzz, Vox Accent Bender, Z.Vex Down Factory.

edit Dynamics

Also alleged aggregate and amplitude effects, dynamics furnishings adapt the aggregate of an instrument. Dynamics furnishings were the aboriginal furnishings to be alien to guitarists.5

Boost/volume pedal: A addition or "clean boost" amplifies the aggregate of an apparatus by accretion the amplitude of its audio signal. These units are about acclimated for “boosting” aggregate during solos and preventing arresting accident in continued "effects chains". A guitarist switching from accent guitar to advance guitar may use a addition to access the aggregate of his or her solo.53

Volume effects: Electro-Harmonix LPB-1, Fender Aggregate Pedal, MXR Micro Amp.

Compressor: Compressors accomplish loud sounds quieter and quiet sounds louder by abbreviating or "compressing" the activating ambit of an audio signal.54 A compressor is generally acclimated to balance aggregate and bland a note’s "attack" by black its access and amplifying its sustain. A compressor can aswell action as a limiter with acute settings of its controls.55

Compressor effects: Keeley Compressor, MXR Dyna Comp.

Noise gate: Noise gates annihilate “hum”, “hiss” and “static” by abundantly abbreviating the aggregate of sounds that abatement beneath a set threshold. Noise gates are expanders, acceptation clashing compressors they access the activating ambit of an audio arresting in adjustment to accomplish quiet sounds even quieter.54 If acclimated with acute settings forth with reverb, they can actualize abnormal sounds, such as the gated boom aftereffect acclimated in 1980s pop songs, a appearance affected by the Phil Collins song "In the Air Tonight".5657

Noise aboideau effects: Boss NS-2 Noise Suppressor.

edit Filter

Peter Frampton's Allocution box

Filter furnishings adapt the abundance agreeable of an audio arresting that passes through them by either advocacy or abrasion specific frequencies or abundance regions.

Equalizer: An blaster is a set of beeline filters that strengthen ("boost") or abate ("cut") specific abundance regions. Stereos generally accept equalizers that acclimatize bass and treble.58 Audio engineers use awful adult equalizers to annihilate exceptionable sounds, accomplish an apparatus or articulation added prominent, and enhance accurate aspects of an instrument's tone.59

Equalizer effects: Boss GE-7 Equalizer.

Talk box: A allocution box directs the complete from a guitar or synthesizer into the aperture of a performer, acceptance him or her to appearance the complete into vowels and consonants. The adapted complete is again best up by a microphone. In this way the guitar is able to “talk”. Some acclaimed uses of the talkbox cover Bon Jovi’s “Living on a Prayer”, Stevie Wonder's “Black Man” and Peter Frampton's "Show Me the Way".6061

Talk boxes: Dunlop HT1 Heil Allocution Box, Rocktron Banshee.

Wah-wah: A wah-wah pedal creates vowel-like sounds by altering the abundance spectrum produced by an instrument—i.e. how loud it is at anniversary abstracted frequency—in what is accepted as a ashen coast or "sweep".62 The accessory is operated by a bottom treadle that opens and closes a potentiometer. Wah-wah pedals are generally acclimated by alarm and consciousness-expanding bedrock guitarists.63

Wah effects: Dunlop Cry Baby, Morley Ability Wah, Musitronics Mu-Tron III.

Modulation furnishings amalgamate assorted audio signals in adjustment to actualize sounds with abnormal tonal properties. Some accentuation furnishings mix ("modulate") an instrument's audio arresting with a arresting generated by the aftereffect alleged a carrier wave.64 Added accentuation furnishings breach an instrument's audio arresting in two, altering one allocation of the arresting and bond it with the changeless portion.65

Chorus: Choir pedals actor the aftereffect choirs and cord orchestras aftermath by itself by bond sounds with slight differences in accentuation and pitch. A choir aftereffect splits the instrument-to-amplifier audio signal, abacus a slight adjournment and abundance variations or “vibrato” to allotment of the arresting while abrogation the blow unaltered.6566 A acclaimed acceptance of choir is the advance guitar in “Come As You Are” by Nirvana.55

Chorus effects: Boss CE-1 Choir Ensemble, Electro-Harmonix Baby Clone, TC Cyberbanking Stereo Chorus.

Flanger: A flanger creates a "jet plane" or "spaceship" sound, assuming a flat aftereffect produced by recording a clue on two synchronized tapes and periodically slowing one band by acute the bend of its reel (the “flange”). If the two tapes' audio signals are afterwards mixed, a adjust clarify aftereffect can be heard. Flanger units add a variably delayed adaptation of the audio arresting to the aboriginal or signal, creating a adjust clarify or Doppler effect.6768 Some acclaimed uses of flanger furnishings cover "Walking on the Moon" by The Police and "Barracuda" by Heart.6970

Flanger effects: Electro-Harmonix Electric Mistress, MXR Flanger.

Phaser: A phaser or "phase shifter" creates a slight bouncing effect—amplifying some aspects of the accent while abbreviating others—by agreeable an audio arresting in two and altering the appearance of one portion. Two acclaimed examples of phaser are keyboard locations on Billy Joel’s “Just the Way You Are” and Paul Simon's "Slip Slidin' Away".71

Phase about-face effects: Electro-Harmonix Baby Stone, MXR Appearance 90, Univox Uni-Vibe.

Ring modulator: A ring modulator produces a resonant, brownish complete by bond an instrument's audio arresting with a carrier beachcomber generated by the device's centralized oscillator. The aboriginal complete beachcomber is suppressed and replaced by a "ring" of cacophonic college and lower pitches or "sidebands".6472 A notable use of ring accentuation is the guitar in the Black Sabbath song "Paranoid".73

Ring modulator effects: moogerfooger MF-102 Ring Modulator.

Tremolo: A tremolo aftereffect produces a slight, accelerated aberration in the aggregate of a agenda or chord. The "tremolo effect” should not be abashed with the misleadingly-named "tremolo bar", a accessory on a guitar arch which allows the amateur to actualize a vibrato or “pitch-bending” effect. In transistorized effects, a tremolo is produced by bond an instrument's audio arresting with a sub-audible carrier beachcomber in such a way that generates amplitude variations in the complete wave.7475 The guitar addition in the Rolling Stones' "Gimme Shelter" appearance a tremolo effect.76

Tremolo effects: Demeter TRM-1 Tremulator, Fender Tremolux.

Vibrato: Vibrato furnishings aftermath slight, accelerated variations in pitch, artful the apportioned semitone variations produced by itself by opera singers and violinists if assiduity a individual note. Vibrato furnishings generally acquiesce the aerialist to ascendancy the amount of the aberration as able-bodied as the aberration in angle (e.g. “depth”). A vibrato with an acute "depth" ambience (e.g., bisected a semitone or more) will aftermath a dramatic, ululating sound. In transistorized effects, vibrato is produced by bond an instrument's audio arresting with a carrier beachcomber in such a way that generates abundance variations in the complete wave.75 Guitarists generally use the agreement "vibrato" and "tremolo" misleadingly. A alleged "vibrato unit" in a guitar amplifier in fact produces tremolo, while a "tremolo arm" or “whammy bar” on a guitar produces vibrato.7778 Vibrato effects: Boss VB-2 Vibrato.

edit Pitch/frequency

Pitch/frequency furnishings adapt angle by altering the abundance of a complete beachcomber or abacus new harmonies.

Pitch shifter and harmonizer: A angle shifter raises or lowers (e.g. "transposes") anniversary agenda a aerialist plays by a pre-set interval. For example, a angle shifter set to access the angle by a fourth will accession anniversary agenda four diatonic intervals aloft the addendum in fact played. Simple angle shifters accession or lower the angle by one or two octaves, while added adult accessories action a ambit of breach alterations.

A harmonizer is a blazon of angle shifter that combines the adapted angle with the aboriginal angle to actualize a two or added agenda harmony. Some hamonizers are able to actualize chorus-like furnishings by abacus actual tiny accouterment in pitch.79

Pitch about-face effects: DigiTech Whammy, Electro-Harmonix POG.

Delay/echo: Delay/echo units aftermath an answer aftereffect by abacus a alike instrument-to-amplifier electrical arresting to the aboriginal arresting at a slight time-delay. The aftereffect can either be a individual answer alleged a “slap” or “slapback,” or assorted echos. A acclaimed use of adjournment is the advance guitar in the U2 song "Where the Streets Accept No Name".80

Delay effects: Boss DD-3 Agenda Delay, Electro-Harmonix Deluxe Anamnesis Man, Band 6 DL4, Roland RE-201.

Looper pedal: A looper pedal or "phrase looper" allows a aerialist to almanac and afterwards epitomize a byword or access from a song. Loops can be created on the atom during a achievement or they can be pre-recorded. Some units acquiesce a aerialist to band assorted loops. The aboriginal bend furnishings were created with reel-to-reel band application a band loop. High-end bazaar band bend furnishings are still acclimated by some studios who wish a best sound. Agenda bend furnishings charm this aftereffect application an cyberbanking memory.81

Looper effects: Boss RC-30 Bend Station.

Reverb: Reverb units simulate sounds produced in an answer alcove by creating a ample amount of echoes that gradually achromatize or "decay". A bowl reverb arrangement uses an electromechanical transducer to actualize accordance in a bowl of metal. Bounce reverb systems, which are generally acclimated in guitar amplifiers, use a transducer to actualize accordance in a spring. Agenda reverb furnishings use assorted arresting processing algorithms to actualize the reverb effect, generally by application assorted acknowledgment adjournment circuits. Rockabilly and cream guitar are two genres that accomplish abundant use of reverb.82

Reverb effects: Electro-Harmonix Holy Grail, Fender Reverb Unit.

edit Feedback/sustain

An EBow

Audio acknowledgment as a adapted guitar aftereffect has been pioneered by guitarists such as Jimi Hendrix. It is generated by arena an apparatus anon in foreground of an amplifier set to a top aggregate axis the accent into a acknowledgment accent with absolute sustain. Typically, these acknowledgment tones about-face bound from basal addendum into overtones. It can be difficult to get acknowledgment conditions, because it depends on the complete aggregate and on the position of the guitar about to the loudspeaker8384

The EBow, a handheld pickup/string driver, uses two baby coils. One braid has a abiding magnet. It picks up the cord beating agnate to a guitar pickup. The electrical arresting is amplified for active the additional braid which acts as a alluring cord disciplinarian to beat the string. By this acknowledgment bend a bow-like always abiding complete is generated. The EBow can drive one cord at the aforementioned time. Latest EBow models accommodate a approach about-face which allows the amateur to change from basal agenda to overtones acknowledgment sustain 63.

Other alluring cord drivers use the guitar auto arresting as input. Guitar congenital accessories such as the Sustainiac Sustainer and the Fernandes Sustainer actualize acknowledgment sustain with a cord disciplinarian army in the guitar.

Many compressor pedals are generally aswell marketed as "sustainer pedals". As a agenda is sustained, it loses activity and aggregate due to abbreviating beating in the string. The compressor pedal boosts its electrical arresting to the defined activating range, hardly assiduity the continuance of the note.85

edit Added effects

Envelope follower: An envelope addict activates an aftereffect already a appointed aggregate is reached. One aftereffect that uses an envelope addict is the "auto-wah", which produces a "wah" aftereffect depending on how loud or bendable the addendum are getting played.8687

Guitar amplifier modeling: Amplifier clay is a agenda aftereffect that replicates the complete of assorted amplifiers, a lot of generally analog “tube” amps. Adult clay furnishings can simulate apostle cabinets and miking techniques. A rotary apostle actor mimics the doppler complete of a best Leslie apostle arrangement by replicating its aggregate and angle modulations, overdrive accommodation and appearance shifts.88

Pitch correction/vocal effects: Angle alteration furnishings use signal-processing algorithms to re-tune adulterated accentuation in a vocalist's performance.89

Simulators: Simulators accredit electric guitars to actor the complete of added instruments such as acoustic guitar, electric bass and sitar. Aces up simulators acclimated on guitars with single-coil aces ups carbon the complete of guitars with humbucker aces ups, or vice-versa. A de-fretter is a bass guitar aftereffect that simulates the complete of a fretless bass. The aftereffect uses an envelope-controlled clarify and voltage-controlled amplifier to “soften” a note's advance both in aggregate and timbre.90

Boutique pedals

Boutique pedals are advised by smaller, absolute companies and are about produced in bound quantities. Some may even be hand-made. These pedals are mainly broadcast online or through mail-order, or awash in a few music stores.91 They are generally added big-ticket than banal pedals92 and action non-standard appearance such as true-bypass switching, higher-quality components, avant-garde designs, and hand-painted artwork. Some bazaar companies focus on re-creating archetypal or best effects.93

Some bazaar pedal manufacturers include: Analog Man, BJFE, Pete Cornish, Emlyn Crowther, Death By Audio, Devi Ever, Robert Keeley, Roger Linn, Lovetone, Roger Mayer, Strymon, T-Rex Engineering, ToadWorks and Z.Vex Effects.

edit Furnishings assemblage modification

There is aswell a alcove bazaar for modifying or "modding" effects. Typically, vendors accommodate either custom modification casework or advertise new furnishings pedals which accept been modified. The Ibanez Tube Screamer, Boss DS-1, Pro Co RAT and DigiTech Whammy are some of the a lot of often-modified effects.9495 Common modifications cover amount changes in capacitors or resistors, abacus true-bypass so that the effect's chip is no best in the arresting path, substituting higher-quality components, replacing the unit's aboriginal operational amplifiers (op-amps), or abacus functions to the accessory such as acceptance added ascendancy of some agency or abacus an added achievement jack.949697

Tributes by musicians

Effects and furnishings units—stompboxes in particular—have been acclaimed by pop and bedrock musicians in anthology titles, songs and bandage names. The Big Muff, a archetypal fuzzbox bogus by Electro-Harmonix,98 is actual by the Depeche Mode song "Big Muff" and the Mudhoney EP Superfuzz Bigmuff. Lyrics to Super Furry Animals' "Play It Cool" acknowledgment addition Electro-Harmonix pedal, the Electric Mistress flanger.99100 The Nine Inch Nails song "Echoplex" is blue-blooded afterwards Maestro's best answer unit.101 Other songs that advertence furnishings cover "Interstellar Overdrive" by Pink Floyd, "Wah-Wah" by George Harrison, and "Stomp Box" by They Might Be Giants. Joy Division's "Digital" was aggressive by engineer/producer Martin Hannett's AMS agenda adjournment unit.102 We've Got a Fuzzbox and We're Gonna Use It were an all-female British bandage from the 1980s,103 and The Fuzztones were a 1980s barn bedrock awakening band.104

Other pedals and rackmount units

Not all stompboxes and rackmounts are effects. Strobe tuner pedals announce whether a guitar cord is too aciculate or flat.105 A footswitch pedal such as the "A/B" pedal avenue a guitar arresting to an amplifier or accredit a aerialist to about-face amid two guitars. Guitar amplifiers and cyberbanking keyboards may accept about-face pedals for axis congenital furnishings on and off.106 Some musicians who use rackmounted furnishings or laptops apply a MIDI ambassador pedalboard or armband limited controls to activate complete samples, about-face amid altered furnishings or ascendancy aftereffect settings.107108109
