I've always advocated Dimarzio Evolutions - even more so now. My 7 string Ibanez Universe arrived today - I had it customised with Evolution 7's. Best decision I've ever made. They rip all of the other pickups I have apart - very tight and damn heavy for chugging riffs plus they burn like crazy for ripping leads. I've used Evolutions in gutar shops and its always hard to know what they really sound like because of the different gear setups and the fact that you can't really let loose in a shop full of people. I've just shreded the neck senseless for the past 3 hours (the longest session I've had in about 3 years cos of babies) and I can safely say these beat the hell out of Dimarzio Breeds, EMG ZW (81 - 85), Dimarzio Petrucci sigs and everything else I've ever owned. Highly recommended for 6 and 7 string electrics!!
