I have two Tonare Grand Acoustic guitars and one PRS SC-J Limited Edition Archtop. All of them feel like they are top of the line instruments. They were all well over $5000 new. I listed one of my PRS Tonare Grands for sale and made the mistake of putting that it was a Private Stock instrument because the only Tonare listed on the PRS web site currently is a Private Stock version. Mine is Adirondack Spruce over Cocobolo. A collector quickly informed me that my Tonare grand isn't a Private Stock instrument. My SC-J has hand writing on the back of the headstock that says it was a limited run of 300 built from 2008-????. All three of my guitars seem like they are the highest quality that I've owned. I've owned a couple Kevin Ryan acoustic guitars ($18000 guitars) and some other really high end instruments and the PRS guitars are right on that same level. I guess I'm asking what makes a Private Stock instrument stand out over the high end core models that are hand built. Are their different builders building them. One of my Tonare Grand guitars has the label signed by PRS and Steve Fischer but once again not a Private Stock instrument.
