From the vendor
The FX33 Buzz King PCB is a reproduction of the DOD FX33 Buzz Box. This pedal was so bad the sales just bombed so they are hard to find and expensive. The FX33 was DOD's attempt to emulate the guitar sound of the Melvins guitarist/singer King Buzzo. He used a MXR Blue Box and a ProCo Rat. DOD used the Blue Box circuit with their Grunge circuit to create this circuit in a single pedal. Nasty distortion with octave creates a great chainsaw/noise making pedal. Perfect for adding something different to your sound.
V1.2 includes a 3PDT Breakout PCB
