Baritone  27" scale, "Wedge" body, Black Acacia & Adirondack
Yamamoto Jumbo 27, A remarkable instrument by Tony Yamamoto of the Bay Area, designed to be played in open tunings. It's based on a baritone guitar, with a 27" scale and 17 1/8" wide, wedge shaped for ergonomics with the lower bout being 3 1/2" under the arm to 5 1/4" at its widest. Using lighter gauge strings than a baritone, one would tune it to, say, DADGAD, at pitch. The top is Adirondack spruce, the back and sides are black acacia from Australia, which is a very close relative of koa. Tony, a former engineer, has put much creativity and research into this project, the result of which is a remarkable sounding, highly successful specialized instrument. The bass rumbles deep down and fills a room, overall the tone is smooth and rich.

My luthier buddy, Tony Yamamoto, came by yesterday with his latest creation - a 27" scale semi-baritone. Tony designed this guitar to have a big voice in dropped tunings like taropatch and he succeeded spectacularly. He used black acacia, a very close relative of koa that grows in Australia. Here's the back: He used red spruce for the top and included a cutaway: But the sweetest part for me is the wedge shape he used for the body. This makes the very large guitar fit easily under the arm, avoiding damage to old fogey shoulders: The deepest part of the body is a hefty 5 1/2", while the shallow part that fits under the arm is a dainty 3 1/2". Ohhhhhh, I hated to see him leave with this beauty. Fran
