How can I make my MXR FET Driver sound rounder and smoother? Right now it sounds almost identical to my Hendrix JHF-1 fuzz face. I run them both (not at the same time of course) into an SL Drive in SB mode. I want the fuzz to have some edge to it, which it does, but want to smooth out the FET and get it to sound more EJ- ish. Is there another pedal I can add to get a different sound from it. (Other than replacing it with a Dover Drive.) I have both bass and treble knobs all the way down and drive knob at about 3 o'clock. Thanks for any advice.
