The DOD FX20C Stereo Phaser is a stereo phaser pedal with two completely separate outputs. RockBoard's PedalPedia describes the stereo arrangement as letting you send the outputs to two separate amplifiers, giving a tremendous stereo spread, which is what sets it apart from single-output phasers.1
RockBoard's PedalPedia lists the circuit type as digital, and describes the FX20C as an update on the classic phaser design.1
Controls
Three knobs give what RockBoard's PedalPedia calls serious control over the sound of the FX20C1:
| Control | What it does |
|---|---|
| SPEED | Controls the speed of the effect1 |
| DEPTH | Controls the depth of the effect1 |
| REGENERATION | Controls the regeneration of the effect1 |
Speed sets how fast the phaser sweep moves, Depth sets how pronounced the sweep is, and Regeneration shapes the regeneration of the effect, which is how strongly the phaser's notches come through.1
Power
The FX20C runs on 9V DC, center negative, the standard polarity for most pedal power supplies.1
Related DOD phasers
DOD's phaser line includes other models with their own approaches. The DOD Phasor 201 is the company's classic phaser design, the DOD FX20B Stereo Phaser is an earlier stereo phaser in the same FX20 series, and the DOD Phasor 490 rounds out the family. The FX20C's digital circuit and dual separate outputs distinguish it from these analog predecessors.1

Questions
Is the DOD FX20C Stereo Phaser analog or digital?
The FX20C is a digital circuit. DOD describes it as an update on the classic phaser design, so the familiar phaser sweep is produced digitally rather than with the analog circuitry of earlier DOD phasers like the Phasor 201 or the FX20B Stereo Phaser.
What power supply does the DOD FX20C need?
The FX20C runs on 9V DC, center negative, the same polarity used by most standard pedal power supplies and daisy chains. There is no battery option listed for the pedal, so plan your board power around a 9V DC center negative output.
Can the DOD FX20C run into two amps?
Yes. The FX20C has two completely separate outputs, which DOD says lets you send the effect to two separate amplifiers for a tremendous stereo spread. That is the pedal's defining feature and the reason for the Stereo in its name.
What does the Regeneration knob do on the DOD FX20C?
Regeneration controls the regeneration of the effect, which is how strongly the phaser's notches are emphasized. Together with the Speed and Depth knobs, it gives what DOD calls serious control over the sound of the FX20C.
