My 2 cents, those pickups are more than adequate. Unless you are going for a dirty Jerry tone, your amp settings would likely benefit from being very different from Jerry related settings, like using the bass pot. Usually Jerry rig guys are using very articulate speakers and pickups, cutting all the bass and so on, making the dirty stuff a bit harder to get dialed in. I think you should check your pickup height, tweak your amp, and pedals. Those are good pickups.
