Thanks for your nice feedback, Rob, Louis and Ken!

@Ken: There is a lot of hand work in the "production" of these kazoos, so it would be rather expensive for a simple instrument. Maybe I'll get some more woodworking tools during the next year (I discovered the joy of building my own instruments just a few weeks ago), so I can think about a small series from time to time.

I think for US citizens it is a lot cheaper to buy some strips of wood and build your own with similar dimensions. Apart from that: in the US there are some great makers of wood kazoos - in Germany I could only find one maker who really makes wooden kazoos without any plastic parts so far.

@Louis: This one is for you: http://mountaindulcimer.ning.com/video/st-louis-blues-kazoo-and-box-dulcimer

Peter, very creative Idea! Have you thought about making them for sale?

Peter, that's just too cool!

I've just finished a second "Kazoonica", where I put the "mouthpiece" on the left (in front of the first one I made with the mouthpiece on the right).

Many blues harpers play the lower holes of their 10-hole-harmonicas most of the time. You can hold this harmonica in your hands exactly like a bluesharper and even create a "wah-wah" effect with your hands...
