The Switcheroo allows you to run 2 different rigs and share the same effects loop of pedals. Plug your acoustic in input 1 and run your output 1 into your DI. Then run your electric guitar into your wah, whammy and drive pedals into input 2 and run output 2 into your amp. Then you can use the effects loop to run pedals that you’d like used through both instruments. Super easy and simple as that. This pedal makes instrument/rig changes a breeze.
