I've installed the pickup around a week ago, so I've had a chance to try it. This pickup is sick, in the best way possible. It has a tight low end, as well as beautiful, highs. I run it without a tone pot, and with only 1x500m volume pot, and it delivers all the signal you need for that modern metal sound without sounding thin or boomy, or going into any extremes in terms of frequency response. It's a huge upgrade to most stock pickups, and probably on par with many $100+ pickups. It sits in the mix right where you need it. I highly recommend it. The cleans/breakup tones are great too with both pickups engaged. This is my second Donlis set, and it won't be my last. Quick delivery, solid packing, great company. Another proof, that you can make pro pickups for 25% of what big companies charge.
I'm very satisfied.
