Re: PRS 10 Tops
Unless you're really into cosmetics, I'd take a look at the CE line. It's the same guitar as the Custom, except with a maple bolt on neck versus the mahogany. Sure, it doesn't have the bird inlays or the supposed "10" top, but IMO the maple neck brings out a more defined tone that can't be found in the Custom. Don't get me wrong, the Custom is a beautiful guitar and has phenominal tones of it's own. But personally, however, I prefer a CE.
Don't let the "bolt on" neck scare you either. Paul Reed Smith originally made CE's with a maple glue in, but for the sole purpose that Paul himself wasn't happy with the tonal qualities of the glue maple on the CE, he changed the entire line to bolt on.
