Yet another fun session from the 2016 Fretboard Summit! This week we hear John Thomas (Kalamazoo Gals), TJ Thompson, Mark Stutman (Folkway Music), Jim Baggett (Mass Street Music), Robb Lawrence (The Les Paul Legacy) and David Sheppard (Lowe Vintage) field questions on vintage Gibson acoustic guitars. Topics include: the many variables found in most vintage Gibsons; solid linings versus kerfed linings; converting ladder-braced models to X-braced; repair headaches; finish thickness and much more.  Sponsored by TR Crandall.
