BOSS offers two types of sturdy metal footswitches for different applications. The FS-5U (silver) is a momentary “unlatch”-type footswitch, and the FS-5L (black) is a latch-type footswitch with an LED to indicate status. Both footswitches can be connected using ordinary guitar cables. Please consult your owner’s manual for compatibility. Works with many Roland pieces, too. MFSKU FS-5U UPC 761294081549
