Two pedals, connected at my right foot.
One is damper, one is vocal harmony on/off
I balance on my left leg more than I'd like, but the added showmanship, and standing face to face with my audience is worth it. If I was on a high stage more often, I might have rethought the position years ago, but as I stated before, I am most often on the same plane as my crowd.
If I played more organ, I'd love to have an expression pedal too, but that's a sparse luxury for me.
