I found this pretty interesting website - Ed Roman Guitars - Yes he sells guitars but he also discusses this specific topic amongst other things...
http://www.edroman.com/techarticles/22vs24.htmFrom the link: an early 24 fret PRS Classic can sound just like a Les Paul plus get the added attraction of a 335 a Strat, a Tele and even a Jazz Guitar. PRS has taken that guitar off the market around 1995....
Factoid 1: A typical Les Paul will always sound muddy when you play chords !!!!!
Factoid 2: A Typical Les Paul is NEVER capable of sounding like a Strat or a Tele. !!!!!
Factoid 3: PRS broke that barrier in 1984 with the introduction of their 24 Fret, 25" Scale handcrafted guitar,
Factoid 4: PRS further improved on it in 1989 with the introduction of the Classic 24.
