Hi, Before I have my bass tech rewire my bass I would like to get a second opinion probably from some of you electronic wizards here. I'm still having trouble dialing in my Moon JB5 bass.Compared to my 74 Jazz w/stock pickups and a Sadowsky preamp it is not nearly as fat and punchy sounding. I don't understand why.The Moon is a really high end well built bass.Swamp ash body, maple neck, great resonance unplugged,plays like a dream but plugged it it is kind of bland.Originally I had an OBP3 and Ultras in it then I switched to Basslines SJB5 pickups and an OBP1(for the lower treble frequency center). It is better now but still not great. On a different newsgroup somebody told me about a modification that he did for somebody that seemed to solve the same problem I have: This is what he suggested: "I wired his preamp the way Bartolini(REAL GENIUS!!!) shows in his diagrams: It's about the flow of the circuit, ... Follow this path--- 1. The pickups are connected to the PAN POT, THEN (IMPORTANT) 2. Output from PAN POT should connect to the "INPUT of the PREAMP"(NOT the volume pot) 3. The "OUTPUT of the PREAMP" should connect to the VOLUME POT (#1 LEG - Left side viewed from top) 4. The Center Leg(#2) of the volume pot SHOULD CONNECT to the "HOT side of the OUTPUT JACK." Does that make sense?Has anyone here tried this?
