I call my '79 Yamaha FG-375S Jumbo Folk guitar a dreadnought wannabee. The lower bout is 1/2" wider, and the waist is 1/2" narrower, but it's all solid wood, Sitka over rosewood...with a fabulous voice, and beautiful wood marquetry. I found it in the local music store, and it was love at first strum! In pristine condition, I thought it was new but later discovered it was 5 years old (1984). Whoever bought it new took very good care of it. It's fully opened up now, and sounds better than the day I brought it home.
