I just swapped the stock ceramic pickups and wiring out of my MIM Strat and replaced the whole thang with parts from a G&L Legacy Tribute. I'm not totally sure but I think the Tribute models get the same pickups as the American made ones.
It was a transformation of immense joy and wonder! The G&L alnicos are so much sweeter sounding and that Passive Treble Bass system.. oh my god. I'm almost embarrassed for Fender that they're still using their silly old setup. The PTB offers so much more versatility and is an utter joy to fool around with. The neck pickup in particular is rendered chameleonlike by this circuit. It goes from boomy to Ernie Isley in zero flat with a twist of the bass knob.
Hats off to G&L once again. Every encounter I have with their products leaves me totally impressed and appreciative of their dedication to doing everything Fender does but doing it better.
