I just got it home yesterday so I haven't yet had a lot of time with it (I haven't had a chance to play it with anybody else yet at all nor have I played it through any of my bigger amps yet, just the Katana, the Monoprice 5w, and thru the digital interface some). So these are all still kind of first impressions. Two of my other nicer electrics my only other "strats": A G&L USA S-500 and a Fender USA Strat so those are really my only point of comparison.
It feels and sounds great. The fingerboard feels great, I was worried the 7.5" radius would throw me off but I don't notice it at all really (not nearly as much as the 12" radius on the S-500 throws me at first). I was surprised at first to find the the tremolo was decked, but I guess that's how Mayer likes it. I prefer a little bit of float and of the three the S-500 trem feels the best/smoothest, then the strat, then the PRS, not that I use the trem a whole lot though and when I do I tend to just do a Bisby-esque waggle of it. Tuners are locking and seem nice although they have some kind of plastic or something key which matches the truss rod cover.
The finish is black although it's a slightly sparkly black which appears grey in some light--when you're playing the scoop in the lower cutaway reflects the light so it always looks grey there. The neck finish is a fairly thin nitro and feels nice, the neck carve feels very much like the Strat. I mean, the guitar feels very much like the Strat--I think it may be a little bit lighter, the frets are noticeably more rounded/smoother but otherwise it plays very much like the Strat. The G&L is the heaviest of the three by far, but it's a swamp ash body.
*So far* and with the caveat that I haven't exercised it that much yet, it sounds great. I have a set of Fender CS 69 pickups in the Strat which also sound great but these sound a little higher output and a little fuller (?) in every position. I rarely stray from the Neck and Neck-Center on the Strat, I think I'm more likely to use the other 3 on this guitar. 2 and 4 do have the "Quack" although it sounds a little different from the Strat, almost exaggerated. Sounds fantastic though.
All three are Strat-shaped so all three kind of disappear when you're playing them, but the PRS is the *easiest* to play. Not by a lot, but I'm guessing it's the especially well-maintained fret ends (and maybe smaller fret wire, not sure?) but it does feel very easy to play, not that the other two are difficult (they are probably the three easiest playing of my guitars with the possible exception of the Agile AD-3200MMC). I got it for a price that I think I could break even on if not make much, but at this point I don't intend to sell it.
