This video, via Perfect Circuit Audio, captures showcases sound design with a Koma Field Kit, a Koma Field Kit FX and a giant wrench.

They note:

“The Koma Field Kit & Field Kit FX are a fun set of tools and effects for electro-acoustic music including contact mic pre-amps, mixers, frequency shifter, delay and spring reverb, voltage controlled radio and a few other handy utilities.

We used a circuit bent hard drive from Gieskes, a giant wrench instrument and Jesse Dean scratch fader with the Field Kits.”
