A busker in Bath, England plays the fiddle and accompanies himself on a guitar controlled with his feet! Check out the marvelous contraption that makes it possible. -via Arbroath
Now this is genius! Plus, if I were to hazard a guess if he was wearing old timey clothes he could call his invention steam punkish for its brilliant use of gears and other doodads.
You figure a good fiddler is probably stomping his foot to keep time anyway. Only limitation I can see is the number of chords, looks like he's got maybe nine? (Left food rack.)
I recently went to Bath and this guy was there, one of the girls I was with asked him some questions, he said the reason he made the machine was because all the guitar players he met all had bad attitudes, this way he didnt have to deal with any of them.
I saw this guy playing in Corn Street, in Bristol - the machine's pretty cool. I think the pedal he's pushing with his right foot plucks the strings and the pedals on his left foot control the chord using a pneumatic system of sorts. Ingenious!
