I got a cheap Fender Mustang PJ and I was thinking of routing a cavity for a Gibson style neck mudbucker for it as a fun project. The pickguard covers that area, so it doesn't have to be incredibly clean, which is an added bonus. I've heard that mudbuckers have really high impedance levels, though, and will drown out any other pickups. I was thinking of keeping the three way selector as is and putting in a roller pot a la a jazzmaster to control the mudbucker's volume before the main volume pot, since the control panel is a bit tight as it is and I think roller pots are cute. I'm pretty good at brainless soldering but my electrical engineering knowledge is pretty minimal. Will I introduce more tone suck by adding a new pot to my bass? Does anyone have any suggestions for a more elegant solution? I don't really care for stacked knobs, and I'm also not really interested in 5-way strat selectors. Also, I've heard you can get a big tonal variation by introducing a series/parallel switch to mudbuckers. Would that still have a large effect when combine with the tone from the P pickup?
