I have many different Dimarzios, mostly in alder body super shredders. I have the Super D (which is by far my fav, but I know you didn't care for it). I have a tone zone, it's hot, but sounds a little too scooped (darker) to me, but might be better for you. It's articulate, just not enough air for me. I have the Blaze that came in my Universe, but I thought they were rather lifeless, just a flat response, blah. I switched those out to an Evo and a PAF combo. The Evo sounds pretty good, tight, with a little more air. The PAF in the neck sounds really good, not too thick, like some hb's can be in the neck, but chunky enough to get that Petrucci solo sound. I also have an Evo in a RG760, which sounds good; pretty much like Vai (which is what I was going for with this guitar).
I bought the Petrucci crunch lab set that he was using a few years back. I was really disappointed with it. I was hoping for a higher output full sound. It isn't as hot as the Tone Zone or the SD, and sonically falls somewhere in between. I suppose I can dial the amp in to work better with them, but that guitar became a back up to a backup, mostly because of the pickups, so they don't get much use.
As others have probably said, what are your amp settings, whose sound are you going for as a starting point, and are you boosting? For me, without knowing that the SD was one of the hottest pickups, I bought an Ibanez USA Custom in 94 that was my favorite for years, that came loaded with the SD. I didn't even know, I just knew I loved the way it played and sounded. As I bought more guitars and started swapping pickups, I always compared it to my #1. All of the other pickups lacked the air (and output) that the SD had. I never put 2+2 together, I just thought that I needed to raise or lower the height of the new ones. Nope. Eventually, I bought a Charvel USA San Dimas, that I put a SD in and it was night and day from the previous pickup, and it sounded just like my number #1. This guitar has now become my #1, so you never really know what your sound might be, until you try.
