I just thought I'd chime in here. I have the Rebel Yell neck in an ESP Eclipse and it is fantastic. I've heard many people say it's like a Cold Sweat neck, but brighter. I can't comment on that as I've never played the CS neck. But the Rebel Yell neck is great for shred. I find when shredding on it, it is tremendous fun. My only downfall is that I now play my Eclipse a lot more than my other guitar which I use for solo work. The downfall being it's harder to play on the higher frets haha. But I discovered these qualities when playing Vinnie Moore style music, as well as Synyster Gates style shred solos. The notes are just super articulate. The strange thing with these pickups is that it makes you play better. But not in a "it makes you work harder" kind of way. I just found, when I was learning the solo to Lifeforce by Vinnie Moore (check it out if you want to know what I mean), I started off at a lower speed and built up. And now when I play the solo, it sounds so smooth, articulate, and clear. I originally thought it must have made me a better player as I originally just thought because they were so clear, it made me aware of my mistakes, so I learnt to play it properly. But then I went to play the solo on my SD Jazz, and it sounded really muddy, and almost like my playing was sloppy. I can't explain it, but I just love the Rebel Yell neck. The thing that's an added bonus is that it has a great feel to it as well for more emotional guitar playing. I just thought I'd add this in anyways :)
