I've never been a hige DiMarzio fan. I tried a SuperD and Super3 and a pair of Evos but just didn't like the sound. All that changed recently when I got my 2008 USA Charvel SoCals which come with a ToneZone and Evo neck, and I really do like them! They definitely sound a bit more raw than the Duncans I've been using for years, and I find that to be a good thing.
Am I dropping my Duncans for Dimzos? No.
But I'm definitely a fan of the ToneZone in the bridge.
And I must concur on the height of a ToneZone affecting its tone. On the SoCals, they're cranked almost all the way up - you can clearly see the baseplate just under the pickguard opening - and to me that's the best place for them. They're still a bit under the strings (non-recessed Floyd and all that) but right where I would have set them anyway in relation to the string when fretted at the last fret.
I backed one down a tad and was amazed to discover how much like a Duncan JB it sounded - Holy Wars Intro Tone achieved!
However, the JB is by far my least favorite pickup ever, so the TZ was immediately cranked back up to where it belongs
