Holy balls!!! This is easily the best pup I've ever played. Just installed in my Jackson Dominion with series/parallel switching. Already have a Duncan 59' in the neck and it matches surprisingly well. The overall thickness is tremendous but not overpowering. The clarity is astounding across the board and sustain is sensational. I have a 300k vol pot that it's wired to which actually works out perfectly for me. I was afraid it might dull the dynamics and output of the pup but that isn't the case at all. Seems to take just the right edge off the high end so you get the perfect amount of treble and cut without any shrillness/harshness. Actually, I'm positive it'd sound just as good with a 500k, but it sounds perfect for my tastes as it is so I'm not going to change it.
Overall, the perfect pup for me with plenty of power, clarity, chunk & grind. Oh, and cleans up amazingly. Just giddy and happy and wanted to share!
