I've got a early 70s vintage FG-110E (I think that's the model anyway, FG stands for 'Folk Guitar'). I bought it nth hand (meaning I don't know how many owners it had) from a fellow where I work whose wife wanted to get a little extra $ to buy a guitar she liked better. This model was one of the first acoustic-electrics that Yamaha made, has a pickup affixed across the neck-side of the soundhole and has high-hat volume and tone knobs. This is a medium-size body guitar -- larger than a parlor, smaller than a big auditorium or dread model. Has a relatively short scale neck. It plays relatively well, though not nearly as loud acoustically as my D-35 and doesn't hold tune as well as the Martin. It's good for having handy for a quick run through a song or two but I still pull out the Martin when I'm seriously practicing.
