I just got Crawlers installed in my LP, and they definitely seem live up to Tim's description of being very versatile, sounding good with blues, heavy rock, and metal stylings.
And I love the neck pup! It's DC 7.6K Alnico IV (same as used with the Abraxas), with a very sexy smoky thing going on. Even just running into GarageBand's "Classic Rock" amp preset the tone is pretty fab. Ramping up the gain, you can go pretty metal, but thing stay smooth and very responsive.
I know the Miracle Man neck is Alnico and perfectly capable of dishing out tones that are not a million miles away, but of course the MM neck will start off more compressed/saturated than something like the Crawler. (As an aside, isn't the Cold Sweat neck basically the same as the MM neck?)
