My favorite? Is to set it up with my volume on the guitar all the way down strum & then raise the volume on my guitar & get a killer effect. It's not a very ubiquitous pedal I use all the time & loads of people have improved on this idea. But for my tastes this works fine and is a ton of fun. I have not used it on really any other sources besides guitar yet. Definitely something I should explore soon though. Great pedal, loads of fun. Got it while on tour -in Nashville if I remember right? No regrets.
