1970 Gibson B-15/LG-0 Flattop Guitar
This Gibson has one of those odd serial numbers that doesn't seem to fit exactly. It should read as a 1970 model but it does have features of a '68 or '69 model instead. Traditionally this should be called an LG-0 model as it's ladder-braced, 00 in size, and solid mahogany throughout the body. In this period, though, the LG-0 was transitioning into the B-15 model which is often just an LG-0 with a smaller (Melody Maker-style) headstock and weirder "big rectangle" bridge.
B-15s can also be seen very similar to this one but with a spruce top, ply back and sides, spruce top and ply back and sides, solid mahogany top and ply back and sides, or any sort of variation of these mixed elements.
Anyhow, this one is a customer's guitar and received a neck reset, fret level/dress, modifications to its replacement bridge, cleaning, and setup work. It's now playing on-the-dot and has plenty of saddle height for later adjustments to be made. The owner additionally had me install a K&K acoustic pickup, so it's ready for the gigging-road as well.
Intriguing oddities include a narrow nut (typical of late-'60s Gibsons) and really-curvy fretboard (Gibsons usually run about 10" radius at this point but this one is roughly a 7" radius).
Repairs included: neck reset, fret level/dress, new bone saddle, bridge reglue, bridge adjustments, cleaning, setup, and K&K pickup install.
