Well, after much deliberation I have decided to not add a pedal. I am just going to have to be good at adjusting fast the pedals I use with the Les Paul. I tried three new pedals and determined I didn’t like any of them as well as what I have. I could use an identical one... I “may,” and if I do, I think it would be another Scarab Deluxe. I tried an Archer, Fetto and Earth Drive. All were ok, but just duplication of what I can already do with Knob twittering.
