The Marshall PEDL-91009 programmable 4-Way Footswitch gives compatible Marshall CODE Series amplifiers expanded hands-free control over presets and assignable amp functions. Designed for CODE25 and CODE50 amplifiers, the footswitch operates in both Preset Mode and Switch Mode, allowing players to recall stored presets, change banks and access functions such as effects control, tuner and tap tempo directly from the floor. Its programmable 4-button layout makes the PEDL-91009 a practical performance and practice companion for players who want streamlined control of their CODE amp without returning to the front panel.
