Ok, it is time. Let me put this into three categories:
-bridge: Rebel Yell hands down. Got it in a Ibanez S Series and damn, anything rock is delivered so tight, alive, and punchy, with a screaming midrange and a highend which is present and cutting but extremly overtone rich so never sharp, even in such a light guitar. The most fun PU to riff on and my favorite bridge pickup to play leads on since it does the screaming agressive all out alternative to the neck soooo well and makes Skid Row style pinched harmonics around the 12th during your solo just fly off. A classic sound faithfully brought to modern times. Brilliant.
-neck: Has to be the unpottet 10th Anniversary neck. Got that set in a Epiphone Lucille. The most lush and amazing clean and low gain sounds, absolutly pure and alive. Jazz or bluesy play is an expressive joy I have never had before. Also reacts better to tone and volume than anything else I have tried. Pile on the gain and you may not get a great shred tone, but it breathes that warm Slash mojo. This PU, some gain, Sweet Child O Mine...no words.
-set: Sorry to stirr the unobtainable GAS, but the 10th Set takes it. I was never one for the middle position, but any set that makes me like that has a huge upset. The two just work in such harmony it astounds me still. Thought from the same wood they are very different, but put them together and they just match. Beautiful.
Honorable mention when it comes to sets to the RY with a IT middle. Outer coil split RY with that gives an amazing tele like vibe.
Mule in the neck also deserves a name, before the 10th I think it was still my favorite, forming a set with the RY bridge and IT middle.
