The Goya GA420 was a dreadnought acoustic made in the 1970s, most likely of Japanese origin. The GA420 had a laminated spruce top, mahogany back and sides, rosewood fingerboard and bridge and deluxe individual machine heads. The Goya GA420 acoustic guitar seems to be a model unique to the Canada market. The inside label does not reference it's country of manufacture not Sweden or any other country during the period that C.F Martin controlled the Goya brand name.
Interesting observation: There is a serial number label attached to the neck block on the one in the photograph that says "Takamine serial number 78023262" ... Yes Takamine - with the word Takamine printed in the usual script style used on today's Takamine products. Any insight as to why this is?
