The front half of the circuit is based on the Tone Bender MKII, employing silicon transistors instead of germanium ones, which can mean an even louder, nastier Bender. After the third transistor, the signal encounters the second half of a Rat circuit, which it?s a pair of clipping diodes and a clever single-knob tone circuit.
This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 4 knobs for 6,3mm shaft separately.
