I might bid on this hoping that the mojo won't work.
I'm a bass player too....and I suppose you can tune a banjo anyway you want.
...yah just can't tune a fish.
(I'm sorry.....)
And then, there are some players who never learned how to tune the instrument correctly.
In a decade or two, it won't matter, most of us who really can play, and those who listen to such, will be long gone to that trad jazz heaven? in the sky.
Besides which that banjo in the picture is a 5-wire...not my flavor.
