This photo set
of so called ‘trash can music’ instruments is beautiful. I wish I could hear what they sound like. The guitar in the middle incorporates a bundt pan, a lunchbox, and some excellent woodworking skills. About the details, maker Mike Tracz says: The f-holes were cut
and filed by hand and the etching is a quick sand blast treatment. Just enough to rough it up without removing the protective coating.
