Zonk Machine in excellent condition. This is a really wonderful pedal with some rare parts that he does not put in all his Zonk pedals.
Some speak from the builder:
Long sustain, lots of textures and minimum artifacts. Is loud as feck but it cleans extremely well with the guitar volume knob.
This one has one Telefunken AC131, one Texas Instruments 2n4061(as the original) an one Texas Instruments 2n5438 germanium transistor. Big british made PIO TCC capacitor, Philips electrolytic and tropical fish and F+T capacitors. Carling footswitch, switchcraft jacks and Alpha pots, the volume one as a switch that cuts the battery.
