Here is an old box full of old guitar and bass strings, going back to the 1960s. Seems to be mostly incomplete sets. Some are used. It looks like they’ve been stored poorly so there is some corrosion on some. I would not recommend trying to use these on a guitar at full pitch as I’m not sure they would last. Selling as a nostalgia trip or for a collector. Came from a job lot of someone’s rental company.
