I have a Bugera V22 Infinium and I considering having the tone stack relocated. It is currently after all the the gain stages and is the last part of the preamp prior to the PI. I know the earlier in the circuit the more effect the tone controls have, generally speaking. I would like it to be placed immediately after the V1A gain stage. Has anyone else had this done? If so, were the results worthwhile? It seems to me to be the kind of thing an experienced tech can do in an hour or less.
