Kenoman,
Excellent!
What you have there is an F212. I have 76 model F212 in Sun-burst. It's an excellent 12 string guitar. It has great tones and will stand up to a lot of beating, though now that it's edging close to 30 years old, I'd treat with great respect.
Your 79 model is pre-Fender. Guild Guitar Company was bought out by Fender Guitars in th eearly 80's and the quality went down hill real fast. Fender does have a Guild specific website @
GuildŽ Guitars . YOu can check serial numbers and all there on the site.
I am an avid Guild owner and lover. I own a 74 D-25/6, 76 F212 and a 1980 D212.
I'm am positive you will have years of playing with that instrument. Keep it. It only gets better. As far as value in todays world. It has not depreciated in value too badly. If you wished to sell it, by the looks in your pictures it appears in excellent condition. I would expect you could get 600.00 - 700.00 for it, maybe a little more. [disclaimer ... I don't guarantee that price
] . I'm going by what I've seen sell over the last couple of years. The F212 was the lower end of the Guild 12's. It is the Jumbo Body cut as opposed to a dreadnaught cut. The D series, like my D212 are dreadnaughts. Though Guild made other series, 412/512's which were also Jumbo Body in a slightly larger scale than the F212.
If your dad passed it on to you, I'd cherish it. They do not make them with the quality yours has. It will last you the rest of your life.
Best to you.
