OK I've done a quick search and found a lot of threads mentioning the hums and such that you get from having problems with the bridge/string grounding or grounding in general, but here's the situation. We've got the Talkbass Wish Bass II making the rounds and the second person has mentioned noisy electronics like a bad ground, problem is, it doesn't look like the strings CAN be grounded. The strings are fed through the body without ferrules (just holes drilled through the body a little deeper in back than in front) and the nut is Corian, which i'm pretty sure is non-conductive (not sure but I think the nut is Corian also so you can't just ground one string and have the nut take care of the rest as if it were brass). The first person who had it didn't notice any hum and other Wish users (the satisfied ones ) have said that their instruments are dead quiet. So the question is, is the string grounding necessary, and if so why? I've heard that some active circuites don't need ground wiring but never been told why. The wish has a simple volume only passive circuit, so that shouldn't be the issue but it may be be nice to know why one circuit doesn't need one while another does. Mods, this seemed best here in Luthiers, but if it would be better in pickups feel free to move it.
