Just picked up what looks to be a Royal Blue JB (maybe Electric Blue?) similar to what Tommy Thayer has used in his blue sparkle Les Paul. Is this a standard JB just with a different color made only for him?
15.9 is within spec. Normally it's 10% for Duncans.
I'd say it's just a normal JB with a flashy color. If it were somethign else, they'd probably label it something else. Not to say that's a bad thing, though.
