Quotes from DiMArzio.com on the Evolution Bridge Humbucker:
'The pickup is tight, aggressive...'
'...more harmonic overtones than conventional humbuckers...'
'The Evolution® pickups were originally designed with live gigs in mind, but they have so much presence and definition that they're great recording pickups, too; they slice right through even the densest mix.'
'Low notes are very tight, and the highs have a lot of presence, enabling the pickup to be heard in almost any situation.'
As a 10 year long user of EMG 81's and 85's I can tell you that the remarks from DiMarzio about the Evo are fact, not opinion.
I was pretty happy with my sound and got the Evo just to hear what the hype was all about. I was amazed.
The clarity, tightness and definition are tits. It's got plenty of gain/power. It sounds more lively than the EMG, the highs are more articulate and there's so much more harmonics the guitar seems to sing. It's tighter than my EMGs. Solos cut right thru.
The Evo 2 is supposed to be even better and the D Activators, man if they're that much better than the Evo... holy shit. I did my comparison with my only guitar thru my only amp and it was like night vs. day. I don't plan on buying EMG's again. I can't really see how the D Activators can be better but if I were to get different pickups, it'd probably be one of them.
That said, I played a Schecter C-1 Classic with the JB/Jazz combo and although they weren't as striking as the Evo is they were better than the EMG's to me too. Not as much power as the EMGs but in every other way they were nicer.
Just my $1.95... Here's a $2 bill. Keep the change!
