The Marshall PEDL-90012 2-Way Footswitch is a replacement dual-button footswitch designed for compatible Marshall DSL Series amplifiers including DSL5CR, DSL20CR, DSL20HR, DSL40CR and DSL100HR models. One switch controls channel selection between Classic Gain and Ultra Gain modes, while the second switch activates or bypasses the amp’s FX loop for streamlined pedal integration. Integrated LED indicators provide visible status feedback during performance, making the PEDL-90012 a practical floor-control solution for DSL players who require quick access to core amp functions.
