I've played a PRS singlecut and a Petrucci music man. PRS pickups in the singlecut were nice and brute; not as bright as Burstbuckers since PRS' can be a little muddier/bassy (in a good way, love my McCarty). I can tell you that the Tremonti obviously caters to his sound but I've read things around from Paul himself about the singlecuts how they're all kind-of out to cater to the big rock bands around just like Alterbridge etc. As far as the JPMM, I've also played it like I said and its got a very thin nice smooth neck. you can tell i don't know real specs. about guitars but more just feels, and the Petrucci is cool. Got the piezo on it. The action was a little high for my liking on it and seemed a little too high for being a shredder's guitar, and the Bridge pickup seemed way too low. The pickup switch is also not as on the go but then, has the singlecut (read: Les Paul) pickup switch ever been easy? The JP has good reach on it though, most likely better than the SC with its 24 frets I think and very deep cutaway on the super thin neck. It's almost like a trapezoid taper on the neck, little squareish but comfy.
