I have bought and installed these pick-ups into an Ibanez RG 350 DXZ . I paired them with a SHR-1B Hot Rail in the middle. To say I basically have a new guitar tone-wise is a total understatement! They are so much more punchy and potent than the stock Quantum pick-ups that where in the Ibz.
If you're looking for the authentic Black Metal sound, look no further. But don't be fooled into thinking these are a one trick pony kind of deal. They are so much more versatile than i expected. The sound is more treble/midrange oriented, they are not as strong in the bass as the Nazgul/Sentient for example, but they are much better than the Duncan Distorsion they are based on! Also, these are the BLACKENED Black Winter pick-ups, with hex screw poles, not just the simple Black Winters , and they have white covers to match my guitar's color scheme. Honestly, what more to ask for?
