Hey all,
A buddy was offered an Epiphone steel string NV-390 for purchase. I had a look at the guitar for him, no problems, two minor dings, great sound, action, looks. Hell I'd snap it up myself. I did however promise to check in with the 'experts', that's you, to see if anyone knows anything about these (MiJ and probably decade(s) old) as well as get an idea of what it may be worth. Arched back also.
