I haven't yet heard back from Ilitch, so I thought to post here for all your users of the Ilitch Noiseless Tele PGNCS-T Pickguard.
The wiring diagram
makes it seem like I need to separate my pickup ground wires from all the other grounds on the guitar. My lead pickup has a copper baseplate. Do I need to snip the connection between the baseplate and my pickup's ground wire: leading to me grounding my bridge unit separately from the pickup?
Also, will the shielding I did to the guitar negatively affect the system?
Thanks for any help guys!
