Middle Jem Pickup - Useless?
I always thought one of the coolest pickup configurations I've seen was in one of George Lynch's ESP's, it was 1 humbucker that was on rails and had a little electric motor that would move the pickup from the bridge position to the neck position. *I heard a couple of demo things with Lynch playing and the pickup moving back and forth, it sounded really cool, almost kind of a wah / phaser type sound. *The only downside was the guitar looked pretty crappy with a trough cut all the way down the middle of the guitar but talk about making 1 pickup a versatile pickup!
Back to the original topic, I use the single coil on my Jems and UV's quite a bit, mostly for anything bluesy, I don't know what I would do without it really, besides, I think guitars with HSH config look better than just 2 Humbuckers.
But that's just my opinion.
