OK, so maybe you are all sick of me talking about my new toy/tool, but I'll type anyway:
I did a quick comparison of my P24 and the P245SH. I played a riff or portion of a song on one guitar into my looper, then did nothing for a similar amount of time while still "recording". Then played same thing (hopefully) in the blank space. I repeated this for a few different settings/styles: I did some dirty stuff and some clean. This let me hear the guitars while not actually playing.
Obviously the differences in the physical build of guitars are potentially going to make just as much of a difference as the pickups: stop tail vs tremolo; 24.5" scale vs 25"; 22 frets vs 24; semi-hollow vs solid. But even still there seemed to be something from the pickups that were different.
58/15 pups rock! Compared to the P24 with 57/08s, they seemed to have more clarity. The P24 has a bit darker sound compared to the P245SH.
One thing that was a really nice bonus was that the P245SH is lighter than the P24. Although the semi-hollow seems like an obvious factor, the P245SH seems thicker, so it could have been a bit of a wash.
Also, although not glaringly different, when I was conscious of it I could feel the difference in the neck width (Pattern vs Pattern Regular).
Oh, and the split coil or coil tap mode enabled when pulling on the tone knob is a really nice feature - the split coil 58/15 seems like a slightly clearer, more polite, mode, which makes for good clean sounds and dirty tonez with added clarity.
After doing my comparison I got lost in some jamming and goofing around. And that was icing on the cake - I love getting lost in the tonez and just rocking out or whatever (sometimes I go off into soundscape land, where there is no "beat", just washes of sound swirling, looping, and falling...).
Anyway, I like this guitar. I like all my other PRSi too! Speaking of which, I need to mess around with that SAS a bit more...
