A random question just ran through my head... If I bought a Bass Big Muff, could it do double duty and work on my guitar the same as a normal Big Muff would?
Yes, and it sounds INCREDIBLE. I use mine for both, and it's fantastic on both instruments. The only downside is having to redo the knobs back and forth when you switch, but that's not really an inconvenience, it's just that when you forget and try to play the other instrument, it sounds like total ass for a minute.
I love using bass distortion pedals on a guitar, so much more balls.
