My Hawaiian style diddley bow, or doodley bow, is 30" long and 2.5"wide and 2" inches tall. I used a guitar tuning peg, a Hawaii mint tin and some scrap wood to build it. the paint job was done with acrylic paint and paint pens. I also used a metallic gold pen for the outlines. Small felt pads were stuck to the bottom of the feet.
In the video I am running the diddley bow through the iShred app and into my iPad. The app Loopy was used to record my loops. The drum tracks were put down with a Roland Handsonic 10. The lead synth was done on my Korg Kaossilator Pro running through another Kaoss pad. A Griffin iMic was used as the audio interface for the iPad and a Korg nanokontrol was employed for midi control.
I had some trouble getting a clean signal and for some reason the recording came out very low too so I used garageband to help bump up the levels and reduce some of the hiss and shape the sound. Another problem I keep running into is the nanokontrol kept getting flicked off for no apparent reason.
