It's loud, foul, soulful and dirty. It works extremely well with a down-tuned guitar. It seems like a lot of people prefer the original, but I don't. I actually sold an original 1978 Dirty Fingers to replace it a reissue - they have more bite, sound brighter (but not buzzy), and contrary to the old ones, these are wax potted. If you're looking for a warm, aggressive sounding pickup, or make your Gibson sound like a Gibson with more output, I can't recommend the Dirty Fingers enough.
