I know Dave's JB/Jazz combo, but was that was he used in Peace Sells/SFSGSW?

When Dave was playing Bc Rich guitars, he was using what came stock on the guitars, Dimarzio Super Distortion bridge, and Dimarzio PAF neck.
When he switched to Jackson, he started playing the JB and Jazz pups.
Good to see that Dave left BC Rich when he did considering Neil Moser left the company and BC Rich has not been the same since. Moser custom shop makes better BC rich style guitars than BC Rich does.

Sorry I got a little off the subject there

He also used the JB in the neck!

He used the Custom for a while, didn't he?

I read that he used a Custom in the bridge and a JB in the neck, at least that's what the Jackson Mustain model had.
