A Slimmer, Simpler Take on the Alpha Omega

The Darkglass Alpha Omicron was created for the bassist who wants the Alpha Omega's premium analog signal path and dual distortion modes in a smaller pedal format for less money. Clank and djent are this pedal's strong suits. But thanks to a Blend control, players can unlock subtler shades of dirt with ease. Choose or mix between two distinct distortion flavors, tap into added thickness and presence via the Growl and Bite controls, then layer onto your dry bass tone to taste. Like all Darkglass pedals, the Alpha Omicron is proudly handmade in Finland from the finest parts.

Two variable distortion modes

The Alpha Omicron borrows the Alpha Omega's dual-distortion engine to provide virtually limitless shades of bass drive. With the Mod control rotated fully counterclockwise, the Alpha distortion's punchier, tighter fuzz better suits rock and progressive music. On the other end of the spectrum, the Omega's spankier, gnarlier effect is great for soloing and modern forms of metal. Bassists at Sweetwater tend to favor somewhere in the middle. Once you find the sound you like, blend to taste with your dry signal using the Level and Blend controls.

Darkglass Alpha Omicron Bass Preamp/Distortion Pedal Features:

  • A slimmer, simpler, and more affordable take on the Darkglass Alpha-Omega
  • Premium analog signal path
  • Two blendable distortion modes
  • Blend dry signal with wet signal continuously
  • Independent distortion Drive and Level controls
  • Growl switch (shelving bass boost) thickens low end
  • Bite switch (2.8kHz high-mid boost) adds presence

Darkness from Finland

From the shores of a dark glassy fjord comes a creature of darkness. Hard to see but alway present, darkness made manifest. This creature howls in raspy tones that sets speaker cones to shiver. Even when blending with the background. The tones are cold with the touch of madness associated with only the eldest of gods. The creatures drive for distortion knows no bound s, and just a little will drive your tones into a dark scary place. Somewhere in Finland, some guy scoops up these creatures up and shoves them unceremoniously into a metal gray effect petal that tortures it with 9v.

Ace Of Spades

I had a gig that required an overdriven "this one goes to 11" sound. While my bass amp can deliver the same overdriven tones as this pedal, doing so would create a substantial blast radius with no possibility of survival. Whether you are channeling your inner Lemmy, bringing heft to a punk trio, or delivering doom to the masses, this pedal is the way to go.
Rated 5/5

This Pedal ROCKS!!

This has to be one of the best pedals I've had in a long time. Other brands I've used don't have the control that the Alpha Omicron does. Between the blend and other features, this has become my "go to" pedal for overdrive and gain. We just played a debut concert at a local music theater and not only was it easy to change settings as needed between songs, it added just the right amount of dirt and grind to punch through and drive the songs home!! In my opinion, this pedal wins !!!
Rated 5/5

METAL PEDAL!

I was in search for a bass tone that had gain but kept its clarity and low end. This pedal does just that. My sales engineer Taylor recommended this pedal and it's a beast. My band plays in Drop B and I play thru a SWR Workingman 4004 amp head with matching cabs, 4x10 and 1x15. As soon as I activated this pedal, it shook the walls, literally (lol). I set mine to more of the "Alpha," settings, the low end boosts and the grit sound blends well. If your in search of a good distortion pedal for you bass rig, this is it. Definitely worth the money!!
