Swineshead Pickups:
In general:
I got GITD bobbins, and I'm somewhat disappointed with the dim glow. They definately glow, but the light output is only about 20% of what my GITD knobs are doing.
The backplates are huge. Very thick, rectangular, with plenty of unnecessary material. I had to chop the corners off in order to fit the pickup in the cavity, and it's a pretty large cavity. I would have had to have done even more chopping if they were going in my rg7620. The instructions they came with were short and sweet.
CL7N-
I ended up slanting this pickup by accident so that the bass side is slightly closer to the neck than the treble side.
This pickup packs quite a punch for being advertised as a medium-output pickup. It sings very well with plenty of bass and mids. Wired in parallel, it really doesn't seem to lose much output, and gets a very nice nasal tone to it. In series, it sings with a great deal of clarity, it reminds me of the AN7N, only with a tiny bit more bass.
HT7B
This pickup seems to lack the balls I had hoped for. Not quite bright enough for my tastes in bridge pups. The tone is clear and focused, but rather punchy in the mid. This isn't a bad thing, it's just not what I expected. I'd compare it to a TZ7B with some of the mid shifted to lower mid. It cleans up wonderfully.
Overall: You know, for the money, I would think you could do better. I'm very happy with the CL7N and I'm moderately satisfied with the HT7B, but I think my tastes are more in tune with the clarity and power of EMG's, or at least the diversity of the Dimarzio AN7/EVO7. My draw to these pups was purely cosmetic, and I'm not even blown away with that.
IMO- These are good aftermarket pickups at a premium price.
