^ the neck version of the cold sweat is alnico V, as far as I'm aware, it's the bridge version which is ceramic.
the cold sweat cleans are quite nice- but I'm not sure I'd call them "airy". That's possibly partly due to the guitar they're in, the amp I play through, etc. etc., but if I wanted an airy clean tone as you stated, I'm not sure I'd want the cold sweat, kind of thing. I don't have any experience with any of the other bareknuckle neck pickups, but I'm sure there are other, lower output, more "airy" neck pickups in the BKP range. Don't get me wrong, the cold sweat in the neck isn't metal hot or anything like that, and the cleans certainly aren't "bad", but they aren't amazing, and it doesn't really sound like a vintage output pickup either, to my ears anyway; it's warmer and smoother and takes to high gain a lot better.
When I asked Tim for pickup recommendations (and he recommended the cold sweat in the neck), I asked for "good overdrive and decent cleans", and I'd say that's about right- if the overdrive is your priority, go with the cold sweat- you'll still get nice cleans, but they probably won't blow your socks off. If clean tones are the priority, then perhaps go with something a little more vintage in tone. Funnily enough, I actually asked Tim about an airier Cold Sweat in the neck for a possible future guitar (a custom superstrat), and he suggested an alnico IV Mule, but I haven't tried it yet, as I haven't got the guitar or the pickup yet. :lol:
With the nice review from Dave_MC, the CS might not be a bad call then !
thanks :D
