This is the newer version of the MkII pedal. It has an added tonestack, so you can alter the amount of treble, mid and bass on the pedal. We have also added a buffer. Both the buffer and the tonestack can be switched competely out of the circuit if desired, thus turning the pedal into the MkII version.
The pedal uses the highest quality components and, like the MkII, has an AC128 germanium transistor.
