I've had one for the past few years now and tried a couple of different Carvin pickups in the bridge position, but the guitar always sounds too smooth and silky. I can't tell if that's from the guitar or the pickups.
It`s the pickups. I`ve had more than few Carvins(not that one) but whenever I put Duncans or Dimarzios in them, they come to life. Growl, squeal, whatever you need them to.
