GutBucketeer, you beat me to the punch this time. I was going to mention OneMan Johnson. I don't actually consider myself a one man band. I play 'pre'cussion with a very crazy looking washboard/sound effects gizmo but I haven't even been doing much of that lately. Though, when I do drag it out, I still get comments from listeners that refer to it as a one man band. I've enjoyed building it and adding to it. It becomes a fun challenge to find items to add and then an interesting design puzzler to add them to the mix where they can be functional among all the rest. I've never tried to take it in the direction of becoming a one man band only pre-cussion and soundeffects fun. My friend OneMan has been very influential on many aspects of my performance style. I have even collected a number of items thinking that perhaps I'd try my hand at creating some kind of one man band for myself but have not yet ventured there.
Kaleea, that corncob item was produce by Hohner. It's whacky looking to be sure. I almost bought a used one once because it looked so very odd. I tried to find a picture of it online but I was not successful.
This thread has produced some nice results so far.
Saw ya later
