Serial number PB 3033? What is that? And the Certificate says "SG Custom Q". So I just call it "Q". Master Grade one piece Quilt Maple top. The best 3D quilting I've ever seen. I've never seen a headstock or fretboard inlay on an SG quite like these either. It even has ebony knobs. So all in all, the most custom lefty SG ever made? You are going to want to see all the photos on this one. $5995.
