Randy's Revenge

The Randy's Revenge by Fairfield Circuitry is a ring modulator pedal featuring the following technical specifications and features:

- Input Impedance: 1 MΩ
- Output Impedance: 1 kΩ
- Power Supply: 9 to 9.6 VDC
- Current Draw: 85 mA
- True bypass
- 1/4” mono input/output jacks
- 1/4” stereo CV jack
- 2.1mm DC connector
- 4.7” x 3.8” enclosure dimensions

Key Features:
- All analogue, hand-stamped
- Pure sine wave oscillator
- Low-pass filtered with a touch of class
- Expanded control voltage (CV) capabilities
- Stereo CV switch-programmable for use with an expression pedal or as a 2-channel CV port
- Voltage-controllable oscillator and low-pass filter frequency
- Internal oscillator available as an output, turning Randy into a stand- alone voltage-controlled oscillator (VCO)

Additional Components:
- Voltage-Controlled Oscillator (VCO): Generates a low distortion sine wave with frequency control
- Four-Quadrant Multiplier: Multiplies two signals to create sum and difference of all frequencies involved
- Voltage-Controlled Low-Pass Filter: Affects only the modulated signal, not the clean one
- Input and Output Sections: Buffered by a discrete JFET gain stage, providing an ideal interface for instrument level sources and a characteristic tone

Powering:
- Designed to operate using a typical center-negative, regulated 9-9.6 VDC power supply
- Protected against reversed polarity and overvoltage conditions
- No battery connection inside the pedal

Warranty:
- Fairfield Circuitry offers a 2-year warranty from the purchase date, covering repair or replacement of any malfunctioning product
- Problems resulting from modifications or misuse may cancel this warranty
