The BOSS FS-5U is a momentary ("unlatch"-type) footswitch designed for tasks like tap tempo, effect triggering, or loop station control. It activates a function only while pressed, housed in a sturdy metal chassis with switchable polarity for wide compatibility with pedals, amps, and keyboards.

This pedal is fully tested and functional. Pedal has some minor cosmetic wear from normal use (scratches and scuffs).
