The Basics of the Phaser Effect The phaser effect operates by blending the instrument's input signal with a phase-shifted copy of itself. Doing this filters the audio and causes cancellations at various frequencies depending on the amount of phase shift. As the degree of phase-shift changes, the cancellations and filtering sound shifts up and down the frequency spectrum.
The phaser has three modes: knob mode, tap mode, and auto mode. knob mode The speed of the phaser is set with the speed knob and the speed range switch. The fastest speed range will give you ring modulator type sounds.

When the mode switch is set to knob, the ratio/speed knob sets the speed of the phaser. width – determines how far the phase shift varies from the center position in tap and knob modes. The higher you set this the more pronounced the phasing effect will be.

DIP switch inside the pedal. Engaging the Harmonic Enhancement Circuit Engaging the circuit can be done by opening up your phaser and locating the ‘BLEND’ dip array. Switching DIP1 on or off turns the harmonic enhancement circuit on and off accordingly.
Expression Pedal Configuration The pedal ships in this configuration. Plug an expression pedal in to the control jack on the right side of the phaser and use the expression switch to select which parameter you’d like to control with the pedal. You can select speed or width when using knob and tap modes.
Midi Control The Empress Phaser allows all of its digital parameters to be controlled via midi control change messages and to have its tempo changed with midi clock messages. To use midi with your Empress Phaser you’ll have to:...
1 period of the phaser’s waveform. Warning: Changing the speed/ratio knob when midi clock is being sent will confuse the phaser. It will momentarily switch to the knob setting, and then switch back to the midi clock setting causing general chaos.
