I bought this guitar for £20 ($25) yesterday and I don't know what it is. Can anyone help me?
Headstock photos would really help. Though, considering you bought it for $25, I'd say it's firewood (unless the seller knew absolutely nothing about it).
How does it sound? Any identifying marks on it?
No real identifying marks on it, however there is a "10" stamped inside it. It sounds quite bright, but slightly banjo-y. And yes, the seller knew absolutely nothing about it. It was her fathers, but he passed away and gave it to her, and she didn't want it so she sold it.
Sorry mate, no sweet clue. It's definitely old, but I'd recommend taking it to a luthier and try to have him ID it.
