Alpha·Omega Engine™ to add natural compression, 

organic harmonic enhancement, and saturation 

ranging from mild overdrive to high gain bass rage.

The Alpha·Omega Engine operates before the clean 

section (you can therefore use the 6-Band Active EQ for 

additional tone shaping).

BITE

: Boosts high mids (2.8kHz) for additional 

presence and definition.

GROWL

: Shelving Bass Boost for a fatter tone and 

increased low end saturation.

COMPRESSION

: This knob controls the amount of 

dynamic compression added to the Alpha·Omega 

Engine. The make up gain is adjusted automatically. 

The compression can be turned off or assigned using 

the Darkglass Suite.

DRIVE

 : This knob controls the amount of distortion 

that the Alpha·Omega Engine will deliver. It will 

change from a soft, warm overdrive to a massive and  

modern distortion sound.  

LEVEL

 : Use this knob to control Alpha·Omega Engine’s 

output volume.

BLEND

 : Use this knob to mix between the Clean signal 

and the DIstortion signal (Alpha·Omega Engine).

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.

GAIN

 : Use this knob to change the volume of the 

signal before the Active 4 Band EQ. You can set it low 

for ensuring the cleanest operation possible or set it 

higher for a more aggressive growl.

BASS

 : +-12dB at 80Hz. Use this knob to change the 

low-end content of the signal. 

MIDS

: +-12dB at 250, 500, 1.5K and 3Khz. This graphic 

EQ control the mid content of the signal.

TREBLE

 : +-12dB at 5kHz. Use this knob to change the 

high content of the signal.

MASTER : Use this knob to control the overall volume 

of the amplifier.

MUTE : Use this push button to mute the amplifier.
