The One Control Minimal Series White Loop is a two-loop true bypass switcher that allows guitarists to quickly toggle between two loops or bypass both loops instantly. The left switch toggles between both loops (Red or Green) and the right switch will bypass the entire pedal. This is a great tool if you want to have quick channel changing but don't want to buy a large switching system. Just like the Black Loop, two DC outs are included to connect power through. The White Loop can also be used as an A/B switch with a mute function. Simply plug one amp into the Red channel Send and the other amp into the Green channel send and the left switch will toggle between both amps. You can also use the pedal as tuner output / mute switch if you connect your tuner to the Send jack of one channel and use the other channel for your regular signal chain.
