The DigiTech FS3X Footswitch not only expands on the functionality of your existing Digitech pedals; it transforms them into completely new beasts. Boasting features like a simple three-switch design, controls for models, mode changes, loop selections, and starts/stops, plus an ultra-compact steel chassis for placement on even the most crowded of pedalboards, the FS3X is a necessity for getting the most out of your effects.
