Let's say we have a simple buffer like here: It's probably totally nooby question, but would it be hard to switch it into a booster? I mean - changing or adding some components with a flip of a switch, so we have some additional gain at the output? Or it would just be better to stick a LPB in there and switch between two pot values?
Forgot to mention - it's going to be a part of a wah circuit. I've heard that boosters cause distortion problems in wahs.
