The Darkglass Alpha Omega Bass Preamp Overdrive Pedal is a fully operational amplifier base and has two distinct distortion circuits (Alpha and Omega) which can be selected or blended using the Mod knob. This unusual control, in conjunction with the toggle switches and 3 active band equilizer makes Alpha · Omega the most flexible among Darkglass designs.

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.

Bite
Boosts High Mids (2.8kHz) for additional presence and definition.

Growl
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, whereas Omega is simply brutal and raw.

Bass
+-12dB @ 80Hz

Mid
+-12dB @ 500Hz

Treble
+-12dB @ 5kHz

Parallel Output
Hardwired copy of your input signal, useful for getting a clean signal in recording and live situations

Direct Output
A balanced version of the ¼” output, useful for running into PA’s or studio mixing consoles.

WARNING
The Alpha·Omega has a current draw of 30mA. Only use a regulated 9V DC adapter with a center-negative plug. Due to ecological reasons it does not accept batteries. Unregulated power supplies and/or higher voltages may result in suboptimal noise performance and even damage your unit, voiding the warranty.
