most of what i build now gets BKP'd... but i am also a big fan of TV jones stuff and bartolini soapbars for basses.
generally if i am after a HB/SC/P-90 then it will usually come from BKP.
I was happy with Dimarzios for a short time shortly followed by swinesheads for a few more guitars. I have also tried PRS's, Gibsons, fenders, SD's, EMG's, Lace's, fralins, vintage vibes, golden age, iron gear, razor, kent armstrongs and probably a few others i cant remember. Many of them have been good and some have been really good - i still think BKP's have a little extra something else
I want to add Lollar's to that list at some point but that will probably be for something BKP dont do like a steel pickup or Charlie christian style tele pickup. I am also wondering about the new lace alumitones - mainly because they look cool and are built so different to any other pickup
