The Boss FS-7 is a compact dual footswitch for remote control of effect pedals or amp channel switching in a durable steel chassis. Two footswitches are arranged in tandem, which saves space on effects pedal boards. Two selectable modes for latch or momentary allow for control of a wide range of equipment. The latch/momentary switching function is common to A and B. Powered via 9v adapter (power splitter included) with battery-free operation (operates as momentary switch with no power, LEDs will not illuminate without AC power.)
