Speakin' of ugly feet, this spring I got a fungus under my right big toenail.
The doc cut it off to grow cultures with.
And dang, that was my favorite one, too.
At least by the time he took it off it had already almost completely lifted off the nail bed so I didn't feel a thing.
I'd been treating it with vinegar for a couple of weeks before the appointment, but he advised that while it might kill what was in the immediate area it still doesn't get the systemic infection, need specific anti-fungals for that, and that's why he wanted to culture the nail to ID the specific fungus. Various types need different fungicides, for a 6-9 month treatment no less.
Still haven't figured out where its came from, it was the first time I ever experienced this. But he said in fact most people will get one at some time in their life.
SO maybe you wanna be a little cautious about acquiring guitars which have been in such close proximity to feet.
Y'never know.
Just sayin'.
