I think the argument can be made that all major guitar manufacturers have upped their game over the last decade. (Yes...even the G company). PRS quality has always been the best in the business. It's really what put them on the map as a company. (In addition to the unique shape, tone, and birds.) Their challenge has been to remain on top which they have done to a remarkable degree. If you don't improve your product, you can't do that so, yes, I think the newer guitars are the best the company has ever made. Fortunately, with PRS, if you buy an early model, you still get a super high quality instrument with perhaps a touch more mojo. I have a 1990 CU24 with SN under 10,000 which for some reason I think is cool. Would I like SN under 1000? Under 100? Sure! No particular reason, I just would. Would it be a better guitar than a 30th CU24? Nope. Would it be a great instrument? Most likely. As gush says above, the most significant change has been pickups. I'm one of the lucky ones that likes the HFS/VB combo. It really works for the styles I play. But...I have to admit, the 09 CU24 I recently bought with 57/08 pickups is more articulate with a meatier tone and that will be the one I reach for when I want to play a Govt Mule tune on a 24 fret guitar. I was just doing the A/B on a the 57/08 loaded CU with a HFS/VB loaded '91 CE last night through my Blackstar. Great tonal differences. As soon as my mood changed though and I wanted to play some old UFO, guess which guitar got the nod? CE. No pickup like an HFS for great pinches and squeals! Rock Bottom!
