In the pic you see a Black Falcon. That's a big guitar; 17".
6120's are smaller. Tennessee Roses are smaller and thinner. And if that's still too big there are Junior models. Most Gretsches are still thinner than your average jazz box.
Some Electromatics are great like the 5120, the Armstrong signature, the Corvette. Others are too much like a Gibson/Epiphone. I do like the fact they gave the revamped models black top filtertrons though.
But I'm not gonna trade in my DeArmond M-75T for one of the (semi) solid Electromatics any time soon.
