The Voodoo Lab Control Switcher allows you to switch channels on multiple amplifiers and automate any non-MIDI functions with ease. Designed to work seamlessly with the Voodoo Lab Ground Control Pro or any standard MIDI-capable foot controller, it offers instant MIDI programmability for controlling amp functions such as channel switching, reverb, boost, EQ, effects loops, and more. Equipped with four fully isolated relays, the Control Switcher features front-panel buttons for manual access, individual 1/4" mono outputs, and a multi-DIN connector for flexible integration. It runs on a standard 9V power supply and is compact enough to be mounted behind your amp, inside a rack, or directly on your pedalboard - making it a powerful and versatile tool for modern guitar rigs.
