Well, a couple days ago I traded my SG for a Charvel. I want to say it's a model 4 but I could be wrong, so please correct me if I am. It has the Kahler trem and the pickups have been replaced with A DiMarzio Tonezone at the brifge and a DiMarzio PAF at the neck. Anywho, heres some pics:
Anyway, lemme know what u guys think.
I don't think it's a model 4 unless it's been modded a good bit, which is quite possible too. A normal model 4 has no pickguard and has a HSS layout with mini switches. From what I can recall though, that's the right logo and neckplate for a model series and I think some came stock with a kahler and then later with the JT6 bridge.
I'd imagine it's a nice guitar though, I have an old model 4 and it's a great player, I've been meaning to try and fix mine up a bit because the bridge is in terrible condition and I wouldn't gig with it like that.
