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?

Goya GA 420

I have a GA420 that I bought second hand in excellent condition in 1978. The Takimine serial number ( which I hadn't noticed until you mentioned it ) is 78023129. On the soundboard truss there is a stamp which reads Feb 17 1978. On the other truss there is what appears to be a small circle with a oriential symbol ( Japanese?) composed of a stretched letter A like symbol on top over a box like symbol with widend top. I may be wrong but I believe the production of these, possibly the last of the Goya brand were subbed by Martin to be made in Japan.

I have one of these as well which I bought in 1978. The year my son was born. I wanted him to know music came from somewhere besides a speaker. It is Japanese handcrafted subbed by Martin. Mine has a forward truss placement which allows for better resonance with less effort. It is really nice guitar to play. I've playing it for 38 years now and it has held up extrememy well.
