The Alpha-Omega 900 takes the best elements of Darkglass' most successful distortion preamplifier ever, combined with state-of-the-art features to make a monstrous 900-watt amplifier with earth-shattering tone.
While Darkglass' signature Alpha and Omega drive engines add incredible girth and size to the overdriven signal, the studio-grade VCA compressor adds an extra layer of control, and the ultra-quiet 6-band graphic equalizer can help sculpt the tone from aggressive and overdriven to crystal clear clean, whatever your needs may be. That's not everything, though. The MIDI programmability and impulse response cabinet simulation, along with up to three storable virtual cabinets, make the AO900 not only one of the most complete amplifiers for touring musicians but also, combined with auxiliary input and headphone output, the ideal tool for silent practicing. The Alpha Omega 900 amplifies the best qualities of one of the most powerful and distinct Darkglass products ever made.
Distortion
Use this push button to turn on or off the AlphaOmega Engine to add natural compression, organic harmonic enhancement, and saturation ranging from mild overdrive to high gain bass rage. The AlphaOmega Engine operates before the clean section (you can therefore use the 6-Band Active EQ for additional tone shaping).
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.
Darkglass Suite
The AlphaOmega 900 integrates seamlessly with the Darkglass Suite via USB, allowing you to load custom or factory impulse responses (IRs) for cabinet simulation and fine-tune your tone for both DI and headphone outputs.
