Interesting that Guild initially released these as a less expensive Studio guitar for students. Initially they came with "Mickey Mouse" single coil pickups. Over time they evolved with Starfire features of humbuckers "hum cancelling" and HB1's, Guildsby, and some had a red mahogany finish, blond and even a deeper body 304 model.
One thing to check out is how well the Guildsby functions. I added one to a 302 model I owned years ago and the neck angle was too shallow.
One thing that is cool about these guitars is the thin full hollow body. Thinner than a SF3, but not semihollow like a SF 4. Kind of a like the Epi dot ( if my memory is correct). I always wanted one of those early SF5's that were full hollow. A famous guitarist from the UK played one. The Guild Studio model can cover that model.
Oh...first thing when you get it...flip the TRC around!
Great snag!
