I'm currently exploring options for bridge pickups for my GT3. Here are my requirements...
1) Nothing ultra-high output. I've already got guitars with X2Ns and Blaze Customs and love them both, but I tend to use this guitar for more textural playing in open tunings, so I want something a bit less hot (although I'm definitely into more modern pickup sounds).
2) It has to balance well with singles, as this is an SSH guitar.
3) It needs to sound decent in split mode.
I have a Steve's Special in one guitar and I really like that, so that's currently number one on the list, although I've been considering the Tone Zone and JB as well.
BKPs aren't really an option due to cost at the moment, but I'm open to any Dimarzio or Duncan suggestions.
What about a P-Rail? If you're doing more ambient/textural stuff, it could give you lots of different tones and textures.
