Ochiai Tadao Japan Vintage Anno 1971 This is a rare piece with a unique pickguard and soundhole design. While Ochiai's entry-level M series features 19 ribs, this model uses 21 ribs and is equipped with metal covers for the machine heads. While contemporary works are also excellent, pieces from the era of the late Tadao Ochiai are still highly regarded today and possess sufficient quality for long-term use. The fingerboard is slightly worn but has no warping or cracks. The string height at the 1st fret is 2.2mm for the G string and 1.8mm for the E string.
