I have a PRS CU22 Trem with a set of Abraxas and really like them in that guitar.
The neck pickup is very much like a Mule, and the bridge pickup sounds like a darker Mule with fatter mids. I find it to be a very versatile guitar, not really an 'aggressive' sound in any way, that can cover a lot of bases.
I can't say as I'm massively familiar with Santana outside of the hits, so can't really say how good they are for his type of tone. Although Id've thought using Boogies and Dumbles, atleast nowadays, is more important than his pickups. That and believing that the amount of sustain he gets comes from his own legs :lol:
