I'm pretty sure they're Lollars. I've had mixed luck with Lollar P90s as the first few sets I encountered in two different Reverend guitars, were kind of sterile sounding, but the guitar that Kuz sold me (H535 P90) has a great set of Lollar dogear P90s, I love them. I guess it's luck of the draw.
A demo of that guitar plugged straight into my Mesa Fillmore 50...
