The Cold Sweats I can't vouch for, but the Crawler set I had in my Les Paul Standard were by far the most responsive, harmonically-rich humbuckers I have ever played. Curse the penury that forced the sale of that guitar! However, it's now rockin' in Iceland so how can that be all bad?
Seriously, although they were quite expensive, I thought the Bare Knuckles I had in that LP made the difference between a good-sounding guitar and an amazing-sounding one. In the past 32 years I have tried most of the major brands, and even some of the obscure ones (anyone remember P.J. Marx pickups?), and to my ears nothing better than the BK's has yet come down the pike.
