PedalPCB Octagon Multi Effect. Slightly modified to include expression input, the knob on the top right selects which of the top 3 parameters will be controlled by the expression pedal. Can also be set to none for standard pedal operation. Big thanks to Madbean forum member ‘bsoncini’ for that one!
Great and slightly bonkers multi effect unit, has some almost Rainbow Machine settings as well as more standard sounds, overall brilliant work by PedalPCB.
Etched with NaOH, the pattern is a spiral made out of Octagons because Octagons.
