Not all stompboxes and rackmounted electronic devices designed for musicians are effects.

These pedal-style tuners usually have an output so that the signal can be plugged into a [[guitar amp]] to produce sound. Rackmount [[power conditioner]] devices deliver a voltage of the proper level and characteristics to enable equipment to function properly (e.g., by providing transient impulse protection). A rackmounted wireless receiver unit is used to enable a guitarist or bassist to move around on stage without being connected to a cable. A footswitch pedal such as the "A/B" pedal routes a guitar signal to an amplifier or enables a performer to switch between two guitars, or between two amplifiers.

Guitar amplifiers and [[electronic keyboards]] may have switch pedals for turning built-in reverb and distortion effects on and off; the pedals contain only a switch, with the circuitry for the effect being housed in the amplifier chassis.<ref>Chappell, Jon; Phillips, Mark (2005).
