Single coils, you say? I would never have guessed that. I assumed they were humbuckers - since they're in more or less a soapbar size & shape. Live & learn...
I truly dig pickups with a rails design over those with a pole pieces design. But not if the magnetic field isn't broad enough to cover all the strings. Kind of defeats the purpose, doesn't it?
Please tell me, Phil: Did Peavey use a very different onboard preamp for the 2G TL5 than the preamp for the 1G TL5? The 1G version had separate, single pots for bass, mids & highs - plus an active/passive toggle; while the 2G version had a stacked pot for bass/treble, and another stacked pot for midrange level/sweep - no active/passive toggle. So I'm guessing that means the answer is "yes".
