I have a barely-used plain gut Lenzner A string for sale. I purchased it new from Gollihur recently, installed it once, left it on for a week and took it off. Never gigged, less than an hour playing time. Like-new condition, "hairs" coming up a bit where it was wound around the peg, but still solid.
It was $85 new, I'll sell it for $65 shipped CONUS, or partial trade towards a Pistoy A.
