Some time ago I bought Gibson Les Paul Studio with Gibson 498T and 490R pickups. This guitar sounds like typical Gibson, dark and deep, with some kind of "growl" in it - really good guitar compared to other Gibsons I played. It sounds awesome in normal tuning, but I'm mainly playing in low tunings such as B standard or C standard and in that tunings my sound becomes very dark, with lots of bass and low-mid, kinda muddy. I'm looking for pickups which will cut low frequencies a bit and add brightness and clarity to the sound. I also like "crunch" in my sound, although I don't know how to describe it. I had that crunch in one of my other guitars while using SD Blacouts AHB1. I can't get much brightness from amp, because I play dark sounding amp - Bogner Uberschall with Ubercab cabinet. I prefer ceramic magnets and rather high output than moderate one. My style of playing demands clarity and "pumping" while palm muting. I read a lot about different BKP pickups and now I know even less than before... I played Aftermaths in sapele body guitar and didn't like it. Any experiences and advice is welcome.
