hi..
I notice on all my ibanez', theres a wire connecting the ground lug of the volume pot to the
trem claw, which is screwed into the wood... I originally presumed this was to ground the electronics to the wood of the guitar - this seemed believable, if a bit strange

... but it struck me earlier that it could be the other way round; grounding the trem and strings to the ground connection from the jack..
So basically what i'm asking is, is there any need (while building a non
trem guitar) to screw a screw into the wood, and connect the ground lug to it?
Cheers
Rob
