I apologized if there's an extremely obvious answer, but seven strings, and acoustics are foreign to me so I know nothing of the companies that make them.
Who makes seven string acoustics, preferably in the $200-$400 range?
I searched the 'bay, Guitar Center, Google, etc, and nothing.
Yeah there's nothing these days. You might find the odd company making them every now and then, I remember there being one on thomann.de a while back.
There's an Ibanez model from back in the day but people charge the earth for them.
