This man wrote a song from scratch every day in 2014. He's now releasing them one-a-day for the whole of 2015.
It's quite a project.
I built him a custom Octavia type fuzz with an octave off toggle and a cartoon rocket graphic.
I designed and etched the board myself and the circuit has some quirks, just a little different from the Tychbrahe Octavia. I always prefer to add my own touch rather than build direct clones of any fuzz.
