The A-50 is very interesting - I have it out in my Family Room (vs. "under the bed"), because it takes up so little room - very thin, with a mid-size body. This keeps my wife happy... I must admit that it looks very cool, too, since an acoustic archtop is not what most people see every day.
Playing chords, it is a little "tinny", especially compared to the dreadnought. But it is very sweet playing single notes, solos, etc. - sounds like an electric jazz box. According to the 60's catalog I have, it was Guild's low end archtop, but it is very well made, and this one happens to be in very nice shape. "Antique burst" type finish, all original as far as I know. As with my other guitars, I get them to play, not collect.
Thanks for asking, walrus
