For reasons unclear, my father has a few boxes of unused spinal surgery equipment and tools in the garage. including a whole heap load of stainless steel rods that are threaded the entire length.
Something had to be done.
So i’ve come up with the Steel Rod Box, rods of varying width screwed in on both ends into a basic wooden box. I’ve included a simple contact mic from a piezo transducer to pick up the vibrations for amplification.
I had no idea how it would sound, so after some playing and experimenting i found it sounds best played with some chopsticks (wagamama ones are good) with a felt coating to soften the blow.
the rods can be easily tuned by playing with the lengths…
