So, I've been playing a UV with a Blaze II in the bridge and a 7620 with a Tone Zone in the bridge for a month or so now, and here's what I've decided:
-I still vastly prefer the Blaze to the Tone Zone, and if I had to play only one of them, the Blaze'd be it. However, while I'd grown fairly sick of the Tone Zone prior to grabbing this UV, I've developed a new fondness for it of late - I don't like it as much as the Blaze, but I think it compliments the Blaze well. They're two very different sounding pickups, but that's a good thing.
-I currently own three guitars, a strat (three pickguard-mounted single coils), a 7620 (two direct mounted humbuckers), and a UV (H-S-H on a pickguard). Of the three, the Strat and the UV sound closest when played unplugged - louder and more resonant with vibrant bass but a slightly "quacky" high end, while the 7620 is brighter but weaker in the bass and quieter. This carries over on the clean channel, where the bridge pickup of my 7620 actually sounds brighter than the (substantially brighter by nature) Blaze II in my UV. My experience with guitars is still fairly limited, of course, but for the sake of discussion let's say that this trait is typical to pickguard-mounted and direct-mounted guitars in general.
In light of that, and in light of the fact that it's comparatively weak bass, overpronounced mids, and slightly stingy highs was what I disliked about it in the first place, I'm guessing the Tone Zone would really come into it's own on a pickguard-mounted basswood guitar, where its highs would smooth out and bass would fill out nicely, giving you a controlled, chunky, singing bridge pickup with ample output and plenty of warmth. It wouldn't have a lot of acoustic snap or ring to it, but that's sorta the point.
Am I out on a limb here, or has anyone else noticed this about these pickups? This could make for an interesting discussion.
Also, does anyone know of a 7-string pickup with similar highs but more bass than a tone zone?
