The question before the House is "Has anyone played a guitar like this, with nine strings?"

Bernard is the only poster so far to even get close to answering. Thanks, Bernard.

Bobert, I have not played a guitar with extra strings, but I have played fretted dulcimer with the melody string (highest string) doubled, which is supposedly the traditional way. I decided that it is a pointless complication, adding nothing to the volume but making it harder to keep in tune. I now use one melody string. (I'm not alone in this.)

I listened to two of Big Joe's videos, and I don't think the extra strings are accomplishing anything, except perhaps to keep people from borrowing his guitar, as he said.
