I have never heard of these before but apparently Bo Diddly got his name from them, hence the little square body guitars he played. I've started teaching again at the school I used to teach at about 12 years ago and this Tuesday I have a student coming in to learn the diddley bow! If you search "diddley bow" on youtube you'll get all the info you need. I already play lap steel slide so it was easy for me figure out a few lessons for my new student(who, lucky for me has no music background). I'm very impressed at the level of musicianship and full sound some of these youtube players get with just one string. There are variations that have any number of strings but my student has a one string model. I'm stoked to play it(GAS alert, I'll probably want to build or buy one now).http://i.imgur.com/sKYglEp.jpg
Whoever called it "rush hour" should not be allowed to name anything else.
