1970s S Yairi YD-402 Vintage Herringbone Dreadnought Acoustic Guitar Near Mint w/ Case, Japan


+ shipping

Up for sale, a 1970's S. Yairi YD-402 dreadnought in near mint, 100% original condition and in perfect working order, complete with the original hardshell case. Crafted in Japan, this S. Yairi model was offered only in the Japanese domestic market, with a tonewood complement and construction inspired by the Martin D-28. The uncle of Kazao Yairi (progenitor of the K. Yairi line of instruments), Sadao Yairi's instruments are highly regarded, and this YD-402 delivers a broad, articulate square shoulder dreadnought sound.

Constructed with an X-braced spruce top and rosewood back and sides, 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 10oz, 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 soft and fairly deep V-shaped profile carve, measuring .895” deep at the 1st fret and .970” at the 9th. The ebony fretboard features Pre-War-style snowflake inlay and pristine original slender fretwire. The guitar plays cleanly in every register, the neck is straight, and the truss rod is responsive and ideally adjusted. Action at the 12th fret measures 6/64“ at the low E and 5/64“ at the high E. The scale length is 25.4", and the nut measures 1 11/16" in width. On the headstock, the original genuine Schaller Yairi-branded tuners have clean chrome plating, turn smoothly, and hold pitch well.

The body features a carved ebony bridge that sits flush with the top, and the original drop-in saddle has modest height, yet offers easy-playing action all the way up the fretboard. String spacing at the bridge measures 2 1/8". The bookmatched rosewood back has a detailed center strip and the spruce top is framed by herringbone binding. Exceedingly well-kept, cosmetic wear is limited to a few minor finish scratches in the clear coat of the gloss finish, and the gloss on the neck profile is pristine.

The original hardshell case is included.
