Heavy Electronics HWY 77 Ultra Distortion CUSTOM #10/11
They say:
This pedal was handmade in Minneapolis, MN in July 2012 with you in mind. Originally commissioned to make a run of 11 Ultra 77 pedals for Rob Wicks at Syd's Guitars (who owns the first Ultra 77)... Sayer Payne was driven to create a unique version of the highway 77 with nothing lacking. He focused primarily on the main op-amp of the circuit, and included a N.O.S. metal can LM741 to complete the circuit.
This pedal is #10 of 11.
