1970s S Yairi YD-304 Vintage Square Shoulder Dreadnought Acoustic Guitar w/ Case, Japan


+ shipping

Up for sale, a 1970's S. Yairi YD-304 dreadnought in excellent, 100% original condition and in perfect working order, complete with the original hardshell case. Crafted in Japan to exacting standards, this S. Yairi model was offered only in the Japanese domestic market, with a tonewood complement and construction in-line with a Martin D-35. The uncle of Kazao Yairi (progenitor of the K. Yairi line of instruments), Sadao Yairi's instruments are highly regarded, and this vintage acoustic delivers a broad, articulate square shoulder dreadnought sound.

Constructed with an X-braced spruce top, bookmatched jacaranda rosewood (Bolivian rosewood) sides and back, and a central third of highly figured chestnut on the back, this guitar delivers the breadth, string-to-string clarity and power one expects from a Martin dreadnought, yet with a refinement that’s distinctly Yairi. The bass register is present and warm without being boomy, while the trebles are round and full. And while you'll find Yairi models marketed via a partnership with Alvarez in the USA, the S. Yairi instruments are far less common and were produced under a different distribution deal exclusively for Japan and other international markets. Weighing 4lbs 12oz, we've had this Yairi professionally setup here at Mike & Mike’s Guitar Bar with fresh 12-53 strings and comfortable action.

The one-piece mahogany neck has a deep V-shaped profile carve, filling the palm and chording easily, measuring .915” deep at both the 1st and 9th frets. The bound ebony fingerboard features graduated pearloid dot inlay and original slender fretwire which has its full factory height, showing only faint wear beneath the plain strings on frets 1-3. The guitar plays cleanly in every register, and the neck is straight. The scale length is 25.4", and the nut measures 1 11/16" in width. On the bound headstock, the original genuine Schaller chrome tuners are intact. These German-made gears have clean plating, turning smoothly and holding pitch well.

The body features a carved ebony bridge that sits flush with the top, and the original drop-in saddle has plenty of height. String spacing at the bridge measures 2 1/8". The back features two pieces of bookmatched jacaranda with broad, dynamic grain patterns, and the chestnut center third is highly figured, framed by detailed marquetry. The jacaranda sides also feature noteworthy bookmatched grain patterns. Crack-free and well-kept, cosmetic wear includes tiny scattered marks on the top, with some faint finish scratches on the body. The gloss finish also shows some isolated spots of light finish clouding on the back and sides. The neck profile is clean with just a few minor marks that are not distracting to the palm while fretting.

The original hardshell case is included.
