EV-5 Expression Pedal

The EV-5 is Boss's standard expression pedal, providing continuous foot-controlled parameter changes to any pedal with an expression input. It's the default expression controller for the entire Boss effects lineup.

Passive expression pedal with a smooth rocker mechanism. TRS output sends continuous voltage to the receiving pedal's expression input. A minimum value dial sets the lowest point of the expression range.

Rocker pedal with single TRS output. No power required. The minimum value adjustment lets you set a floor: the expression never goes below that point, which is useful for parameters where you want a limited range.

The EV-5 is the standard Boss expression controller. Affordable, reliable, and compatible with virtually every pedal that accepts expression input. Not glamorous, but essential for anyone who wants foot-controlled parameter sweeps.
