This is the Bowafridgeaphone (bow a fridge a phone). by experimental instrument maker Iner Souster. He has used refrigerator grates, a broken old speaker, a bundt cake pan, metal salad bowl, and the few other pieces of metal he had lying around his workshop. There are also 36 strings along the body to help with its resonance.

Spines were added to help with bracing, as well as 4 strings along the back to help counter all the tension of the other 36 strings. He had built an unbraced and "spineless" version that spontaneously self-destructed and imploded during construction, as tightening the 20th string proved to be the camel that broke the Bowafridgeaphone's back.
