Re: Take a Charvel from 80's metal to blues!
Do you have a link to the guitar? There is no “Duncan Super Distortion 6”. Does it have the Duncan Distortion set?
Since the Charvels are under Fender ownership and manufacture, I think a standard Strat pickguard will fit. I also think your body is routed HSH meaning basically any pickup combo would fit.
Secondly, the only real difference between a blues guitar and a metal guitar is the guy (or girl) playing it. That being said, I can see why you might want to move away from the Distortion set.
There are a ton of cool combos available, do you want HH, HSS or something else? If singles do you want noiseless or do you not care?
