So here is where things started out Sunday afternoon installing new guts for my 1995 Fender MB-4 bass...
Basically, everything was soldered excepting the grounds. I needed to widen the holes just a bit for the new pots and also fashion a new hole in the cavity for a momentary kill switch (ala Buckethead).
First thing I did though is shield the cavity with some Faraday Tape.

Looks pretty good from the outside!
Below is the finished guitar: New pot assembly from KellingSound88 on eBay and new P/J pickups from Fralin Pickups out of Richmond, Virginia.
All was not without friction however, when I had everything put together the pickups wouldn't engage except when the instrument cable was only about halfway inserted. And even then the momentary kill switch, which did work, had kind of "pop" when activated (this indicated the switch was just cutting the hot wire instead of grounding it as the design was supposed to).
So I figured some kind of short was created when I flattened out the wires into the cavity to put the cover plate back on. Opening everything up I didn't see anything unexpected, so I just took extra care that no bare wire was crossed anywhere then sealed the guitar back up.
Then the bass played extra fine and the instrument cable jack was as normal. There also was just the most minimal of noise at high volume (hiss noise from the original pickups are what started me down this project). The Fralin pickups a superb. Coupled with the new pot assembly I can get everything from an acoustic-sounding low-end to a very crunchy overtone-laden mids/highs.
Unfortunately the momentary kill switch no longer works. Not sure whether there is an internal bad connection that broke. I checked the wires and everything was connected as it should be before re-installing the cavity plate. Right now I am just enjoying the bass as it is. I might look for a different kill switch that will fit the 12mm hole I drilled. Ha, the button looks cool by itself even if it does not actually do anything.
