conductive paint and copper tape shield job.

Postby Rhian Batson » Fri Dec 13, 2013 11:08 pm

So my 90 MIJ P was infected by a irritating hum during my most recent studio gig last week. I took it as a great opportunity to shield the cavity and wire a new harness for it as I have been using this one almost exclusively for studio work this past year and need it to be solid and hum free. So, for about 11 bucks worth of copper tape (with conductive adhesive) and a couple 250k mini pots, I embarked on a fun afternoon/weekend project. Below is my non-techie, pro-beer process.

Step one: Pour beer.

Step two: Apply 5 thin coats of conductive shielding paint.

The instructions say 1 a day but with the help of a fan and NewMexico 10% humidity, I got all 5 done in about 3 hours.

Step 3: While paint dries, drink beer, wire assembly & shield the pick guard.

Super important tip: Be sure not to wire the input jack backwards. [smilie=grinning-smiley-044.gif]

Step 4: Tape up the cavity.

This was a PITA frankly. I never really appreciated how skinny a Precision bass electronics cavity is until I have to stick my fat fingers in there with sticky and uncooperative copper tape. I Got it done but it took a while. Even though the copper tape has conductive adhesive on the back side, I still dropped a few solder points to help ensure everything was conductive. I also ran a segment of guitar string from the pickup cavity to the electronics cavity and soldered that in as well as the ground wire from the bridge. The bass is once again silent. The new pots n sprague cap sound awesome.

Time to pour another beer. [smilie=food-smiley-004.gif]

a lot of people would not consider wiring a bass to be fun (despite the beer) but count me as someone who enjoys that part of bass building. Music on, beer (though usually coffee) poured, and soldering iron warmed up.

very relaxing.

beautiful job too!
