I've recorded this short tune to test a tenor banjo, a six-string banjo and a guitar, after a job on their rusted strings. It seems they sound good now. Somebody could wonder why I didn't replace those strings: the matter is that I've found all my stock of strings widely rusted (Thomastik-Infeld excluded). I'm very disappointed about that, in addition I've found only one set with no rust at a domestic music store . The other 5/6 were rusted!!
