Model: Masaru Kohno No.20
Date of production: 1981
Date of aquisition: 2018
Scale: 660/52 mm
Top: Solid Spruce
Back/Sides: Solid Indian Rosewood
Strings: La Bella 2001 - Medium Hard Tension (Lighter tension than Daddario EJ45)
Remarks: Feels much better under the fingers than most Kohno's from the 70s that I've played, probably due to the neck shape. But also thanks to the thin top, at least my luthier told me so. The sound is really sweet, yet clear and easy on the ears. Excellent sustain and separation. Action is great with much room left on the saddle.
I think 1981 was the last the year of the numbering system? Before the Concert, Professional, Special and Maestro line.
