Intended use

Many effects devices are not designed for a specific type of end user, and as such they are used by electric guitarists, bassists, singers, and other performers (e.g., rackmount compressors, reverb units, etc.). Some effects units are designed for and marketed to specific end users, typically electric guitarists, keyboard players, and bass players. In the 2000s, several new target markets for effects units developed, such as vocalists and acoustic instrument users.

Electric guitar

Many effects, and the majority of stomp-box pedals, are designed and marketed for use with an electric guitar (e.g., heavy metal distortion pedals; wah-wah pedals, etc). Some pedals are designed for a specific genre of electric guitar player. For example, Barber Electronic's Dirty Bomb, the DigiTech XMM Metal Master, the Boss MT-2 Metal Zone pedal and the MXR M116 Fullbore Metal pedal(all are distortion pedals) are designed to produce extreme distortion for metal guitarists. Other pedals, such as the Seymour Duncan SFX-11 Twin Tube Blues Distortion guitar pedal and the Boss Blues Driver are designed to produce the warm tube-amp overdrive sound used by blues electric guitar players. As well, many electric guitar effects are used by performers of other instruments. Keyboardists use wah-wah pedals and overdrive pedals, and some electric bass players use fuzzboxes or guitar overdrive pedals.

Keyboards

One of the most notable effects designed specifically for keyboard players is the rotary speaker simulator effect. This effect was designed so that Hammond organists could reproduce the chorus-type effect of a large Leslie rotating speaker without having to transport the heavy speaker cabinet around. Even though rotating speaker pedals are marketed to organ players, some models such as the Uni-Vibe pedal are also used by electric guitar players (e.g., Jimi Hendrix). Many electric guitar effects can be used successfully with keyboard instruments, and there are some combinations which have become well-known (e.g., a guitar phaser pedal used with a Fender Rhodes electric piano). Some effects pedal companies have taken note of this, and in the 2000s, a number of standard guitar pedals are cross-marketed to electronic keyboardists in advertisements (e.g., the Boss Blues Driver).

Bass

Most effects marketed for use with the bass guitar are the same, or almost the same as the similar effects sold for use with the electric guitar. In some cases, though, bass effects do have unique features designed for the electric bass or the double bass. Bass preamplifiers for double basses are designed to match the impedance of piezoelectric pickups with the input impedance of bass amplifiers. Some double bass preamplifiers may also provide phantom power for powering condenser microphones and anti-feedback features such as a notch filter. Makers of bass distortion (or "fuzz bass") effects claim that bass-specific distortion pedal maintain the low-range bass signal better than distortion pedals designed for electric guitar. Paul McCartney of The Beatles used fuzz bass on "Think for Yourself" in the 1965 album Rubber Soul and Hugh Hopper from the jazz rock band Soft Machine in 1968 and 1969. Hopper's use of the fuzz bass sound allowed the bass to be forefronted more in the band, and take on more of a melodic, lead instrument role. Fuzz bass went out of fashion for much of the 1970s, as the desired sound of the era was a clean "hi-fi" tone. In the 1980s and subsequent decades, bass distortion came back, but mostly in the metal and hardcore punk styles.

Some manufacturers sell bass equalizers, which, while similar in operation and design to an electric guitar graphic equalizer, have a lower frequency range that goes down to 40 Hz or even below. Bass-specific wah pedals and bass chorus effects are also available. Bass wah pedals optimize the frequency of the sweep so that it will work better with the lower range of the electric bass. Some bass chorus effects devices only apply the swirling chorus effect to the higher parts of the bass tone, leaving the instrument's low fundamental untouched. Multi-effects devices designed specifically for electric bass reconfigure the effects so that they are compatible with the electric bass' low range and include electric bass-oriented effects such as a fretless bass simulator effect or a bass synthesizer. Some multi-FX pedals for bass contain modelled versions of well-known bass effects pedals, bass amplifiers, and bass speaker cabinets. Just as some electric guitar pedals are cross-marketed to keyboard players, some electric guitar pedals are cross-marketed to bass players. Some BOSS electric guitar pedals (the AW-3 Dynamic Wah, BF-3 Flanger, OC-3 Super Octave) have an alternate 1/4" jack input for an electric bass which has circuitry which optimizes the effect for the lower range of the bass.

Vocal

Some floor-based effects units are designed for use by singers, such as harmonizer pedals (which add a harmony part to a vocal melody) and pitch correction pedals or rack-mount units. Examples include the TC Helicon VoiceLive 2 Floor-Based Vocal Processor (which vocal backup group); the Electro-Harmonix Voice Box Harmony Machine/Vocoder; the TC Helicon VoiceTone Correct Vocal Pedal; and the DigiTech Vocalist Live Pro Vocal Harmony Processor. Although of these portable, floor-based pedals were introduced in the 2000s, the innovation was largely the way that the technology was packaged into a rugged, road-ready chassis; many of these effects were only previously available in larger, heavier studio rack-mount units. As well, vocalists also use generic effects devices, such as compressors and reverb units. An example of a rack unit designed for vocalists is the Antares AVP Vocal Producer, which includes mic modeling technology, electronic pitch correction, tube pre-amp modellers, a de-esser, and parametric EQ, all of which is designed for use by a singer. More rarely, vocalists might route their microphone through a guitar pedal such as distortion pedal or a flanger to create an unusual effect.

Acoustic instruments

Another newer target market is acoustic instrument players who perform on acoustic guitar, mandolin, violin, and similar instruments. These units are often designed to be "all-in-one" devices that will condition and equalize acoustic instrument signals so that they can be plugged directly into a mixer or PA system. Several companies such as Fishman, L.R. Baggs and Boss make stomp-box pedal style effects units for this market. These pedals typically contain a pre-amp, impedance-matching circuitry for piezoelectric pickups, equalization filters, and a DI output.

Some of the more sophisticated pedals also include a compressor for smoothing out loud notes, a notch filter or feedback detector for preventing feedback howls (a common problem with acoustic instruments), and chorus or reverb effects. Many of these units have a microphone input and phantom power so that a condenser microphone can be mixed with the pickup sound. There is some variation in the format or housing. Many units are pedal-style units which have foot-operated switches for switching between pre-set sounds, activating reverb or chorus effects, etc. Units that are designed to be mounted on a belt clip or placed on a tabletop typically lack foot-operated switches.
