The Switch-3 is a three-button external footswitch designed for TC Helicon and BOSS-style 1/4-inch TRS footswitch jacks. Plug it into your vocal processor and you get hands-free control over harmony, looper, preset up/down, tap tempo, and effect bypass without touching the pedal itself.

Rugged metal chassis, silent switching, and an LED indicator above each button keep it gig-ready and easy to read in a dark venue.
