Looking at the specs, it has a P-90 and their own humbucker style. I don't know the sound difference between those two. Can you point me to some examples ? I know the Les Paul has two humbuckers. How does the P-90 differ ?
"Our custom-wound DP90 in the neck position gives an authentic blues tone making a versatile combination with the vintage Humbucker in the bridge position."
Under "Media" here there are two audio clips of both pickups.
