Every good pedalboard setup needs an amp footswitch or two. If you’re gunning your signal through a Marshall amp, then there’s no better fit than a Marshall footswitch. The Marshall PEDL-00021 five-button footswitch is built specifically for the company’s TSL series of amps. It’s durable, road-tough, and gives you complete one the fly access to your TSL amp’s three separate clean, crunch, and lead channels plus the built-in reverb and the TSL amp’s effects loop.
