Growl Switch: Shelving Bass Boost for a fatter tone and increased low end saturation.
Mod: Selects or mixes between the two distinct distortion circuits: Alpha is punchy, tight with a lot of definition. Omega is simply brutal and raw. On the Darkglass Suite you can assign footswitch control of the Mod to toggle between Alpha and Omega.
Master Switch: Where the level knob controls the output of the overdrive section the Master volume adjusts the overall volume of the unit. Ideal for fine tuning the output on clean mode. It also serves as a DI and headphone volume control. Please note that the volume is not affected by this control when the pedal is on bypass.
Bass: Low Shelf +/- 12dB @ 80Hz
Mid Bands: +/- 10dB @ 250Hz, 500Hz, 1.5kHz, 3kHz
Treble: High Shelf +/- 12dB @ 5kHz
Ground Lift: Disconnects the signal ground on the Direct Output to break any ground loops. Set the switch to either position that has less noise. The switch does not affect the 1/4" output.
Cab Sim: Toggle the cabinet simulation on/off on the Direct Output. This switch completely bypasses all digital circuits and allows you to get zero latency signal when needed.
Headphones: Alpha-Omega Ultra has an internal stereo headphone amp capable of driving a minimum load of 16ohms from the 3.5mm stereo jack. Use the master volume control to adjust the level.
USB: A Micro USB B connector allows you to connect the pedal to a PC/MAC to load cabinet simulation impulse responses to the pedal and control various other settings.
