Well, I've had a careful listen to and researched everything from the Vintage Hot and Contemporary now. Nothing from the Contemporary range is really what I'm after except the Crawler because it would all give me a result that is too close to what I already have with the Holydiver. In that respect, the Crawler is a bit of an odd one out and I'd never really considered that before. I can now understand why people sometimes say it should be in the Vintage Hot section. The VJII is too bright and the same is true of the Emerald, which I've tried before in a CU24. Now as a Holydiver user, I'm clearly a man who appreciates mids but I think that perhaps the Black Dog is a bit too similar to the Holydiver to give me a distinctly different flavour in the same model guitar. That brings me back to my original two and this is where it's tough.
I have two of these guitars and both of them sound the same. They're not particularly bright guitars, certainly not when compared to a Strat but they're not as dark sounding as a Les Paul either. It's somewhere between the two. When I had my Jackson (maple neck-thru) I found that to be quite middy but the PRS guitars aren't as mid focused as that; they're warmer and richer with broader sound. Not sure if that helps you guys.
'Rich' and 'sweet' seems to describe both the Abraxas and Crawler very well so in that respect, both are ideal. The Abraxas sounds great and I really like the sounds I hear but if it's brighter than the Holydiver, it won't really nudge my guitar in the direction of a Les Paul. Being a darker and fatter pickup, the Crawler will do that but whenever anyone mentions the Crawlers, it always seems to be with the proviso 'if your guitar is bright' and that worries me slightly as historically, I've found that pickups with too much bass don't allow the guitar to cut through and some of the notes can be less distinct.
