Hosa FSC-604 Guitar Amplifier Footswitch Pedal

The Hosa FSC-604 is a momentary-action footswitch designed for musicians who need straightforward, reliable foot control over their instruments and equipment. Built with an all-metal chassis and reinforced switch mechanism, it is constructed to handle the repeated force of foot activation during rehearsals, recording sessions, and live performances. The rubber pads on the base keep the unit planted firmly on the floor, preventing it from creeping or sliding during use — a common frustration with lighter plastic footswitches.

One of the FSC-604's most practical features is its selectable polarity switch, which allows you to toggle between normally open and normally closed operation. This means it can work correctly with keyboards, synthesizers, drum machines, sequencers, and multitrack recorders from virtually any manufacturer without worrying about reversed polarity causing the switch to behave backwards. The 10-foot hardwired cable terminates in a standard 1/4-inch TS plug, providing universal connectivity and enough length to position the footswitch comfortably on the floor while your equipment sits on a table, stand, or rack. As a momentary switch, it activates only while pressed, making it ideal for sustain pedal duty, tap tempo input, punch-in/out recording control, and drum machine start/stop functions.
