i play 5 on a regular basis as they are my fathers 2 from friends and pretty much the rest of the line at sam ash in new haven. I've played 2 prs's owned by friends (tremonti, dragon 2) and the whole line at sam ash. to me the prs sounds like this bellow. it just bellows with no real definition. Especially the tremonti. The only good thing i can say about tremonti is that it has a tight bottom end but the top end sounds crunchy and choppy. as for the upper class models. they look nice as all hell to play. have a medium wide/fast neck. Not as wide as a LP which is pretty wide and moderately fast a good balance for me. i like the neck on the prs. feels stable and nice to me. but when it comes to sound. It seems as though the notes are dead when i hit them. But chords are again the PRS's favorite. However i do LOVE the older prs's from the early 90s. I played my teachers a few times and I LOVED it. it was a blues/jazz/rock machine. the thing had a great neck, looked great and SOUNDED great. Singing high end decent sustain and a nice low end. Where as gibsons just have this great organic sound all around. I've played everyone of the gibsons from the fast playing but quite limited melody maker to the les paul supreme. My favorite coming out of the series is the SG from the 80's. Like the one zappa used the heel was below the fretboard so it was "nothing but neck thru 24" it was a great guitar. very expensive though. Another thing i think are cool about the PRS's is the cool stop tails they have where the strings come back up and over the stop tail. Doesn't make up for crappy p/us. Besides what decent shredder or blues or any type of music for that matter that requires chords and individual notes has used a PRS. Navaaro? hes the bottom of the great guitar player heap but i like him none the less he uses a custom 24.
I will admit that prs's do sound good when run through a nice distortion pedal and a reverb pedal. but only after using pedals do they live up to their wood they are made out of. NICE wood not so good guitar
