I just got a mega deal: Radius in fountain blue for 189 with Dimarzio X2N and Fred. The X2N was in the neck :-/ (he routed it for a humbucker) and the wiring was botched so i have to re wire the whole thing. Should be a hell of a player though.There are three coil tap switches and two push pull pots (go figure). So i am going to put two 500k pots in with a three way and a .22 capacitor. It is my first wiring job and should be pretty simple. I just need to know how to ground. I know you soder to the trem plate but where does the other end soder to? It also came with a schaller collar arm already installed. :-) Will post pics when it is all set up/cleaned up.
