Re: NGD
That's one of G&L's coolest humbucking guitars. I had the strat shaped version of it with JB/Hot Rails. For some reason the Treble/Bass circuit in it bugged me, so I rewired it conventionally.
I had a few different Duncans in it, and ended up with a 59B. If I were you, I'd install a C/59 Hybrid in the bridge....either the std or TB version, which ever spacing it is.
