As usual I'm going by what I've read rather than personal experience, but since the guitar is basically an SG with a slightly different body shape, I'd have thought the Holydiver would be way too thick sounding. Same goes for the Crawler.
Does the cedar sound very different from mahogany? If not, I'd have thought it's a choice between VHII, Emerald, Rebel Yell and maybe Nailbomb. The exact same ones I'm dithering over for my SG-X, along with the Riff Raff. :roll:
I agree with Downfader about the GS pickups, they're surprisingly good. I had a singlecut GS2 many years ago and put DiMarzios in it; it sounded horrible so eventually I decided to sell it. When I put the GS pickups back in, I suddenly realised it sounded 100 times better (which isn't meant as a dig at DiMarzio, because I chose totally the wrong pickups!).
