-any Crawler/LP Custom testimonials out there???
Definitely. I've got a Crawler set in my LP Std, and they smoke. They're like hot PAFs with extra grunt in the mid-range, which works out to be very versatile: You've got plenty of power on tap without losing that vintage vibe.
IMO, unless you are looking for a more specific tones (e.g. MM's for Wyldian metal), you can hardly go wrong by putting Crawlers in an LP. (OK, you probably can't go wrong with Mules either, at least if you are after right-on PAF tones ... but if you want higher-than-vintage output, the Crawlers bring it home.)
There are various clips (of, erm, varying quality!) from my Crawler'd LP in the Players forum.
