Earlier this month, Gibson announced a $59,000 reward for the safe return of their 1959-1960 shipping ledger, a book that, if it exists, has been missing for decades. If found, the ledger could shed light on the details of Gibson's production of guitars during a legendary period of time, including the variations found on all those famed, uber-collectible '59 and '60 'Bursts. On this bonus episode of the Fretboard Journal podcast, we talk to Cesar Gueikian (CMO) and Mat Koehler (Head of Product Development) from Gibson about where they think the ledger might be, why they're on the hunt for it, and what they think they could learn from it. We also hear about some new and forthcoming Gibson projects, including collaborations with Jerry Cantrell and Adam Jones, forthcoming Flying V and white SG Custom Shop tributes to Jimi Hendrix, a Slim Harpo ES-330 reissue and a lot more.
