Extremely uncommon Custom Shop Les Paul Custom Studio, with bigsby. Custom Inlayed letters MAC on 3rd 5th and 7th fret. I have no idea who MAC is but I hope you do!! Roadworn stamp on back of headstock denotes the 2006 Gibson charity auction. This guitar is in unplayed condition with hangtags and custom shop case. One very small seam can be seen between the fretboard and neck on the treble side 15th fret can be seen in photo.
