There used to be a player called the dirty johnson who played
a lot of slide with harmonica and so on.I think he was from
Australia,and not sure if he was a member on here?
On you tube his name was 'thedirtyjohnson' without spaces!
Bao, fumanshu as he's known around here, had Mike Pereira make him a lap ukulele. Not sure if it's a square neck, but I think it probably is, as it's got raised strings. He's done at least one YouTube video with it.
