Hi, I decided to shield an old P&J passive bass, it's a lovely bass, but had an intermittent pickup hum and 'static' sounds when not touching the strings. All went well, I copper taped the cavities and made sure the overlap touched the foil on the back of the pickguard. Put it back together, the bass sounded great, crystal clear tone, no hum or weird sounds any more. BUT...the tone had stopped working...aagh.
Btw, the wiring is exactly like this: http://s62.photobucket.com/user/Alex_SSS/media/pj-jbass.jpg.html
but without the extra ground wires that chain to the bridge and neck pots.
Any suggestions?
Thanks.
