Zen-On was a music company in Japan in the late 60’s into the 70’s. They had a lot of companies that built for them. This guitar doesn’t appear to have a model number anywhere but it is modeled after a Martin D28. It plays and sounds wonderful. I own an Alvarez Tree of Life from 1983 that is a fine guitar and this one reminds me a lot of that one.
Some of the best luthiers of the 1960’s, 70’s and 80’s were in Japan, the likes of: Toshihiko Tokugawa, Shoichi Yanagisawa, Hiro Tamura and Saburo Nogami.
