A footswitch is a pedalboard accessory used to control various functions of amplifiers, effects units, and multi-effects processors. It allows musicians to switch between channels, activate effects, trigger loops, or change presets with a simple tap of the foot, making it an essential tool for live performances and seamless tone switching.

Footswitches come in different configurations, from single-button units for basic amp channel switching to multi-button controllers with programmable functions, MIDI capabilities, and relay switching. Popular models include the Boss FS-5U, Electro-Harmonix Triple Foot Controller, and Strymon MultiSwitch, all designed to enhance a player’s control over their gear with ease and reliability.
