Is this just a customized Screamin Demon? The bridge looks to be a Screamin Demon in appearance exactly, while the neck looks the same except the logo is on the opposite coil.
Are you sure we´re talking about a SLATQH (H for Humbucker) Or is it maybe a SLATQM (M for minihumbucker)?
The reason I´m asking is that the markings sound more like a MiniHumbucker to me, a Seymourized one to be exact(And those are usually in the SLATQMs).....A SLATQH should come Factory Loaded with JB/ Jazz.
Can you get a pic of the actual axe, even better the pickups? The pic you posted is originally from the Jackson website
