For as much as PRS say the Custom 24 is their flagship model, there seems to have been a lot of de-emphasizing of it and other guitars like it. Options for necks and colors are disappearing, and there hasn't been a new 24-fret PRS since the core Mira 15 years ago. It's always the same thing, "the neck position doesn't sound right", "the high E sounds too shrill", "just bend up on the 22nd fret" blah blah blah, but my band has a few songs with solos that can't be played that way, or are more difficult to play that way.
It's sad. Paul offered the world a better alternative to the old Strat and Les Paul, and for a while the world was still moving forward musically instead of getting hooked on the nostalgia drug people were into it, but now it's more, "You know what, just give us that 1950s sound/feel with better upper fret access (that is, if they feel 6 strings/straight frets are enough to play their music on)." I can see a day when the Santana goes 22 frets (probably shortly after its namesake retires/passes), and maybe the Custom 24 Floyd (since it's a "metal" guitar, and only metal shredders need 24 frets, right?) remains intact, but all of the other PRS models are 22 frets.
