Pulled this little guy out of a Hammond chord organ a while back. Stuck it on the shelf and let it season. Last week, I cut a base for it out of a piece of oak, and started thinking about a pedal. What's a good idea? I already have an expression pedal, and I'm not a wah-wah guy. The pot is a 250k, but I could swap any value in. I like whacked out, trippy effects. Ideas?
