(Doombuggi's getting a little ahead of themselves and recommending really hot pickups meant more for high-gain metal rhythm sounds, which will not go in that direction at all. Warpigs and Painkillers are very different from each other, and also won't sound "vintage," so that's going in a few different directions and they're pretty much the wrong ones here.)
Perhaps I am. Who knows. It is a considerable thought. With this being stated, a guess a happy medium to consider is the Rebel Yell. It is a happy medium, that is reminiscent of an 80's sound, cleans up well, and can remain tight under concentrated gain. That is what I am currently using in my Les Paul. I tune to C#. For the time being I am using a Maxon OD808 RI shoved through the front of a 1989 Marshall 2203 head. I have to say that its sound quite awesome. I like the Painkillers, and I am interested in the Aftermath and Warpig Ceramic. I have had the Holydiver Bridge, the C-bomb set, and the Black Dog set.
If you are tuning to D standard or higher, the BD totally rule, and can stay pretty focused. They are pretty awesome set, one my most favorite pickups I have ever played.
The HD was cool, but not really all my cup of tea. Same with the C-bomb. I obviously dig the mid profile pickups.
I really enjoy the PK, but with the Maxon, the highs were over the top in the Les Paul. With the the pedal disengaged, I found it more enjoyable, though the bottom end needed to be a bit tighter.
Come to find out in my situation, I believe that I am searching for a more modern sounding amp. So, for the time being, I'm putting off buying any more pickups until the amp situation is solidify. I'm thinking something, Fortin.
I think there are many good suggestions here. Best bet, send an email to the BKP team. They are most helpful, and pleasant to communicate with.
