This modification adds a ring modulator to the Fatman. This mod only requires one chip, an Analog Devices 633, a SPDT switch, and two resistors. Be prepared for some gnarly, metallic atonal sounds!

Parts Required:
1) Analog Devices 633 Balanced Modulator
1) SPDT switch
1) 1 K resistor
1) 2.7 K resistor
