Cipig too bright? They've got plenty of high end, but, wow.
Ah well, whatever
You like the infinities....this I find bemusing - theyre extremely muddy pickups. They sound like they're wound with cotton wool to me.
Anyhow, in that case I think the best pickup for you is probably the holydiver. I havent used it myself, but by clips and reports its got less top end than most BKs, and is very thick but still with characteristic BK clarity.
If that doesnt work, and given that you like the sound of infinities, bare knuckles might not be for you. Its a common characteristic that they have a clear top end.
Or turn your amps prescence and or treble down ;)
And, welcome to the boards.
