This two page centerfold spread came out of a 1977 edition of Vintage Music Magazine.
Daion Co. Ltd. is listed as a distributor at the bottom center of the ad with an address of 5-358 Motomachi, Naniwa-Ku, Osaka 556, Japan and telephone 06/633-6121
This makes sense, as Yamaki (also distributed by Daion) was using Mighty Mite pickups in their high end models such as the YST-800, YJB-800, YPB-700, and YLP-800.
Also listed as a distributor is Rosetti & Co. Ltd in London England, who was the distributor for Daion in the U.K.
