My swamp ash PRS Core is essentially a Studio configuration, with HNN pickups, an ash body, and a maple bolt-on neck. (I call it my Swamp Ash Special although it’s obviously different from earlier SASs. Can’t be sure, but I’m thinking it was a limited run. Any other info would be welcome.) It’s a wonderfully bright and even twangy guitar, obviously veering more towards the “Fender” side of the original PRS concept of Fender-meets-Gibson as a best of both worlds. I dig it.
I also own several maple-on-mahogany Core models, and all I can say is they sound quite different from my SAS. Generally warmer. The closest set-neck Core I own that’s even tonally close to the SAS is a korina McCarty that eats other guitars for breakfast (as the saying goes). Aggressively bright, but in a really cool way. (My McRosie is kinda scared of it! lol) Still, they’re all quite different.
In fact, I like the Studio configuration so much that the idea of buying one of the current set-neck maple/mahogany Studios wouldn't faze me at all, regarding my hesitation at buying similar sounding guitars. I’m pretty sure they’d sound very different.
EDIT: I’ve since come across the old Reverb listing I bought the SAS thru, and it was in fact called a ‘Swamp Ash Studio’ model. Anyone know the background of that model? Limited run? TIA.
