I've got an old Black Russian Big Muff Pi and LOVE the thick fuzz tone I get from it (also the first pedal I ever bought, so the sentimental tone is also on point). However, it has one particular problem I'm hoping someone has seen with it or other pedals before. Basically when I go to turn the pedal OFF, occasionally there's a huge volume/tone drop (i.e. with it disengaged, back to clean tone). I can fix it by re-engaging and dis-engaging the pedal, but it would be nice to consistently have the pedal turn off correctly especially in live settings, vs. having to double tap it quickly to get back to normal. Any thoughts?
