Buy them. That's all I need to say. You need these in your life.Sounds insane! I set up it on my schecter reaper 7 - absolutely killing sound! Thank you Seymour Duncan!Gave my PRS 7-string some much needed bite and sounds like a proper metal guitar now. Be aware that depending on on your guitar, you might have to modify the pickups and/or your guitar with some grinding or shaving. I had these professionally installed and the tech said it was very tight squeeze.I purchased a Douglas brand guitar for cheap, they have good quality stuff but the electronics they use are trash. so, I got the nazgul/sentient set and oh man did that make a world of difference. when switched onto a single pickup they each have a unique tone and attack. used together is where this set really shines though. I highly recommend this set.Beast pickups. They completely revived my Jackson Dinky. I have to throw a review in to balance out the one left as a joke.Edit: I should clarify that they make this guitar sound better for my style and range of playing which is in Drop A through crazy distortion, in the middle of a wide mix. I wouldn't suggest a Nazgul/Sentient combo for someone who likes a tweed sound or twangs around in standard tuning with a high A.I'm a devout Seymour Duncan player and I love these pickups. They're warm, crisp, and clear! Perfect for my playing style!These are some of the best pickups I've ever used. They have a very tight but big sound.These are great pickups. They'll drive your crunch channel plenty but are crystal clear, tight and responsive on the clean channel.
