The Alpha·Omega Ultra is the most versatile bass preamplifier Darkglass has designed. It features two distinct distortion circuits (Alpha and Omega) wired in parallel for responsive distorted tones. It's extremely high dynamic range and six-band active graphic EQ allow for flexible, open tones. The dedicated headphone output and balanced direct output with switchable digital impulse-response cabinet emulation make for an incredibly complete tool for the modern bass player.
-
Mod
Selects or mixes between the two distinct distortion circuits: Alpha is punchy, tight with a lot of definition, whereas Omega is simply brutal and raw. On the Darkglass Suite you can assign footswitch control of the Mod to toggle between Alpha and Omega.
-
Blend
Mixes the clean and processed signals. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob, allowing for fine mix tuning.
-
Level
Sets the volume of the overdriven signal.
-
Drive
Sets the amount of gain in the overdriven signal.
-
Growl
Shelving Bass Boost for a fatter tone and increased low end saturation.
-
Bite
Boosts High Mids (2.8kHz) for additional presence and definition.
-
Master
Whereas the Level knob control 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 volume is not affected by this control when the pedal is on bypass.

Warning
When the pedal is on bypass the master volume does not affect the headphone volume. In this case the total volume is adjustable in Darkglass Suite. With sensitive headphones, the bypass volume can be very loud if not adjusted.
The Alpha·Omega Ultra has a current draw of 130mA. Only use a regulated 9V DC adapter with a center-negative plug.
Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty.
