Gibson Custom Shop 12-String Bass
This 12-string bass was built in 1991 by an employee of the Gibson Custom Shop, Phil Jones. Jones built many prototypes and reissue basses and guitars for Gibson from 1984 to 1999.
This 12-string bass was built as a prototype. It has a mahogany body, maple neck and a 24-fret rosewood fingerboard. It is 34" long scale. The neck has a thin, elliptical profile with a single truss rod.
Gibson Thunderbird-type pickups were used and the controls are the standard Gibson configuration of two-volume and two-tone. A custom Leo Quan bridge / tailpiece unit was used,
Petersson acquired this bass in 2010 directly from Jones, who since he had left Gibson was working in Nashville at Gruhn Guitars. Petersson's timing was perfect in this case as when he walked into Gruhn Guitars, the bass was about to be put out for sale.
