I like my Lesters with stock BB1s and BB-Pros. The GoldTop has Classic '57s in it. I like the lower output pups with Lesters, for whatever reason, they really allow the wood to come through, and they sound f'n awesome with something like my 20thA or a topped out boutique combo. They grind and have a growl.
I have Painkillers (BKP) in my drop tuned, heavy string ESP-NTII. This axe plays aggressive djent style music. The beauty of these pups is that they're not uber compressed, so even though they're typically run through a higher gain head, there's still lots of colour and texture to their grunt. They're extremely rich, and have a bite to them that sets them apart in the djent arena - they cut like nobody's business. Sounds great in split mode too.
I have RiffRaffs (BKP) in a custom Hamer. This guitar does everything well - except the nastiest of metal or hard, hard rock. It's a beautiful sounding, rich, older school style pup with gobs of mids and a nice articulate lowend. Split mode rocks, the neck is syrupy and spanky in single coil mode.
Looking at putting Nailbombs or Aftermaths (both BKP) in my ESP-FRII, this guitar is my stunt guitar. Fast playing and lots of shredding. It's my noodler and it runs through everything... Mostly higher gain.
My Suhr is loaded with stock pups... Neck and Bridge in split shine like a true strat style jangle.
Pups I've used that I may consider again - BKP Mules, Emeralds, Black Dogs. War Pigs not so much.
I guess you can see I'm pretty set on my BKPs. But don't mistake this perception, I love stock Gibby pups in the right Lesters as well.
Peace,
