Backstory: My RD Artist preamp has never worked properly since it arrived in my hands last year. First the compressor/expander function wasnt working properly. Then I started getting some static in the bright mode. It was fine at band practice, but ruined a few tracks we tried in the studio, which was totally not cool. The last straw came a few weeks ago when the neck pickup got really quiet all of a sudden. It didnt actually completely die though, and the pickups are totally encased in resin, so I figured the pickup problem may actually lie with the preamp instead of the pickup itself, so last night I decided to start taking things apart. Action: First thing I did was to start removing the preamp board from the bass. Turns out the Bass and Treble boost/cut pots are soldered directly to the preamp board, so those had to be loosened from the top of the body to get the preamp out. The pickups, switches and volume knobs are connected to the preamp board with little multi-prong clip connectors (not sure what the technical term for these is called), so they were super easy to disconnect. I tested the pickups with a multi meter and as it turned out my assumption was correct. Both pickups measured the same, in the vicinity of 6.5 kOhms. This is where I ran into a snag, and why I decided to start this thread (assuming thered be more problems down the road). I decided to try to keep the entire wiring harness intact and keep all the original components together for resale purposes. Everything was going smoothly until I got to the output jack the nut is jammed on the threads and wont come all the way off. So this is my first stopping point for questions: 1) Anyone have any bright ideas how to get the nut off what Im assuming is a buggered thread on the jack? The nut begins to loosen then jams after a few turns, at which point the whole sleeve of the jack begins turning. I suppose I could re-use the original jack, but I really didnt want to have to un-solder any of the original wiring. 2) Im no whiz, but the existing jack seems to be some kind of stereo or switching jack (most likely for disconnecting the battery when unplugged). It has two prongs and 4 solder lugs. If I need to reuse the jack, I assume this wont be a problem for a passive setup? 3) On that note, Id also like to toss around some ideas for how to wire it back up. I understand the issues with VVTT and the tone controls interacting, but at this point Im leaning towards that type of setup anyway. Other ideas Ive tossed around are VVT, Series/Parallel switching, or going hog wild with stereo outputs and whatnot. Open to discussion. Thanks in advance.
