Switcher/Mixer (or "A/B" pedal)

A switcher pedal (also called an "A/B" pedal) enables players to run two effects or two effects chains in parallel, or switch between two effects with a single press of the pedal.

Some switcher pedals also incorporate a simple mixer, which allows mixing the dry guitar signal to be mixed with an effected signal. This is useful to make overly processed effects more mild and natural sounding. Examples of the use of the mixer function include:

* A wah can be mixed with dry guitar to make it more mild and full-bandwidth, with less volume swing.
* A compressor can be mixed with dry guitar to preserve the natural attack of the dry signal as well as the sustain of the compressor.

Multi-Effects Pedals

A multi-FX pedal is a single effects device that contains a number of different effects in it. Some multi-FX pedals contain modeled versions of classic effects pedals or amplifiers. Some examples include:

* Line 6 POD XT Live
* Behringer V-Amp Pro
* DigiTech RP series
* Boss ME-50, GT-6, GT-8
* Zoom G2 series
* Vox Tonelab series
* Roland VG series

Talk box

A talk box is a musical sound effects device that allows a musician to modify the sound of a musical instrument by changing the shape of the mouth.

The effect can be used to shape the frequency content of the sound and to apply speech sounds (such as singing) onto a musical instrument, typically a guitar (its non-guitar use is often confused with the vocoder) and keyboards.

A talk box is an effects pedal that sits on the floor and contains a speaker attached with an air tight connection to a plastic tube. The speaker is generally in the form of a horn driver, the sound generating part of a horn speaker with the horn replaced by the tube connection.

Stomp box

A stomp box is a small wooden box placed under the foot, and stamped on rhythmically to create a thunking percussive sound. usually a microphone is placed inside to amplify the sound. The sound of the box is similar to a bass drum, and is used for practicality. Stompboxes can be home made or be bought commercially.
