Good condition Boss FS-5L Latching Footswitch. The Boss FS-5L Latching Footswitch is a universally applicable utility pedal that will work with Boss pedals and just about any other piece of gear that takes a switching expression control. This is the "latching" version when means that when pressed, the pedal and whatever function it's connected to, stays engaged until it is deselected. Like all Boss products, the FS-5L is reliable, durable, and will deliver every time. No power supply included. Thank you.
