I don't get what people are moaning about in certain reviews, this pickup is great.
It does exactly what it says it does, remove some midrange, add some bottom-end and top-end, you get all the gain you'd ever need and pinch harmonics & squeals are easier than ever before, not only that but they last forever as well!
It sounds a bit weak on the clean tones, to my ears; but that's what you have the neck pickup for, right!?
The chugs and stops are killer, chugs are crisp and clear, and the stops are completely quiet, there's no hum or static noise (This will obviously vary from rig to rig) when doing a stop; it's quiet when you want it to.
I give this a 10/10 for Metal use; because that's what it's intended for.
Not so much on the cleans or crunch, sure, crunch it can do, but you might want to set your selector to bridge&neck at the same time, as it does sound slightly weak with just crunch.
The high gain tones are powerful and very nice though. :)
