I've had a Spirit GT Pro Deluxe for a few years, and finally decided to swap out the stock pickups. The stock HSH pickups were low output, and sounded kind of lifeless.
For the humbuckers, I chose Dimarzio Transitions in neck and bridge positions, and I'm really happy with them so far. Meaty, with plenty of "grunt" if you dig into the strings. I've still got the stock single coil, and need to replace it as well with something that will be a good match. However, most of the "strat" size pickups have a triangular flange on the base which means they won't fit in the GT Pro. The only pickups I've found which will physically fit are Lace, and EMG, neither of which is going to do what I want.
Does anyone have any good suggestions for the middle pickup?? I'm open to either single coil, or single-coil-sized humbucker, as long as it would match the output and general tone of the Transitions. Preferably something that's easily available (NOT special order with a 6 month lead time).
