"The traffic" 555 timer triple tremolo [flashing lights flashing lights flashing lights]

I built this tremolo pedal based on a simple flashing light circuit.
An instructable on that circuit is here: https://www.google.com/amp/s/www.instructables.com/Flashing-LED-using-555-Timer/%3famp_page=true

The box is pine and recycled hdpe.

I had built a tremolo with this circuit previously, but with one single timer, and that works just fine, but I wanted to do this craziness, and I'm glad I did. It's finicky, and not quite finished, but I know I will be making more music with it.
