but there are head-scratchers....
the color is not McCarty sunburst
the bridge is not the standard PRS piezo bridge
the controls are WAY different than PRS's piezo layout
the pups are not archtop
hardware is not nickel
don't think the knobs are PRS
It Looks like a PRS in general body shape but I bet it started as a non-piezo archtop and was modded by an outside of the factory luthier to add the piezo. I'm also betting that the hang tag serial number and the one on the back of the headstock don't match...
Unless someone from PRS can tell you that it's a prototype or it was modded by PRS, I'd pass - especially at what they are asking....
If I were considering it, I'd definitely ask for a serial number photo and who did the mods.
edit: just like Markie intimates below, I'm not totally convinced it is even a PRS....
