Preamp, DI, and Distortion in One

The Alpha Omega bass pedal from Darkglass Electronics is so much more than an excellent DI. It's also a pedal-sized preamp and a savage-sounding distortion effect. The Alpha Omega was codesigned with Karnivool bassist Jon Stockman and combines a dynamic saturation circuit with a 3-band EQ and balanced line driver. Level, Drive, and Blend knobs dial in and fine-tune your clean and overdriven signals. Growl and Bite switches increase or decrease the Alpha Omega's low- and high-frequency saturation. And dual outputs make parallel processing and running your signal to a PA or mixing console a piece of cake.

Codesigned with Jon Stockman

Karnivool bassist and all-around sonic adventurer Jon Stockman got together with the engineers at Darkglass Electronics to create the Alpha Omega. Because Stockman regularly goes from thick lows for filling out the bottom to grinding, effected tones that jump out front, he knew that he needed a pedal that would deliver any shade of low-end grit he may need at a moment's notice. So while the Alpha Omega can definitely nail cutting, overdriven bass tones to the wall, it is equally at home as a clean, tone-shaping preamp. As Darkglass puts it, "Alpha Omega is the most flexible among our designs."

Powerful set of controls

The secret to Alpha Omega's encompassing personality is its bevy of tone-shaping controls. The Level, Drive, and 3-band EQ are easy enough to figure out. But the real fun comes when you start manipulating the Growl and Bite switches, the Mod knob, and the all-powerful Blend control. The Growl and Bite switches affect the low- and high-frequency saturation of your signal, placing your tone's teeth right where you want it. The Mod knob is a variable way to select between punchy and tight tone or an all-out raw sound. And you can always blend in your original signal to taste.

Effortlessly integrates into your rig

Whether you're a fan of vintage gear, prefer to go straight to the console, or have a complicated rig that would put your guitarist to shame, Darkglass Electronics's Alpha Omega boasts the I/O to make it happen. At its most streamlined, you can run an instrument cable from the 1/4-inch to your amp and take advantage of the pedal's tone shaping. The XLR output makes Alpha Omega a brilliant DI box. And the onboard parallel output lets you send an unaffected tone to one source, and your affected sound to another. Sweetwater bassists are clamoring to add this pedal to their setups right away.

Best bass distortion pedal

I begged my bass player for a year to get a distortion pedal. He did some research and he decided to get this. Holy crap what a difference it made. The low end sounded so powerful and the harmonics and saturation was insane. Do yourself a favor and get this if your a serious bass player.

The Beginning and The End of Bass Distortion

I admit that getting this pedal isn't for everyone considering the price and how many bass players actually use distortion. But if you're only going to have one, let it be this one. By far the most versatile/useful bass distortion pedal I've played with, and it sounds great no matter what.

Whatever tone you think of, this pedal can pretty much do all of it. Subtle dirt, full-fuzz, super punchy riff-attack-dog - and anything inbetween. I use an MXR Bass DI+ in conjunction with this to get more tones (using that awesome "Color" button on the DI+), and between those two pedals, I could do any gig, regardless of genre. I've also used an ODB-3 in front of this as a clean boost to really push this pedal and get more punch/attack out of it, like I'd do with my Big Muff to get a high-gain amp sound for my bass (that still has loads of low-end).

The parallel out is also a game changer when it comes to recording my bass for harder genres of music - I can double track with the clean to maintain the lows and definition of the instrument, and use the distortion to get the gnarly mid-range "horn" that helps the bass to be perceived in the mix.

I'll be using this pedal for the foreseeable future, and I highly recommend it for anyone that needs some dirt on their sound - regardless of genre.

Surprisingly versatile!

Don't misunderstand Darkglass products. They are not only good for aggressive distortion sounds and this pedal is a great example. The active EQ, the bite and growl switches, and the wide range on gain jnib give you a lot of options for dialing in anything from low gain, "tube saturation" tones to very aggressive heavy metal tones. And it sounds great on any settings. And as with all Darkglass, it is well built and durable. Highly recommend!

All of the Beasty Bite and Growl I Was Looking For

This pedal did not disappoint. It has all of the full bodied bite and growl that I was looking for. Even with a somewhat limited amplifier setup, I have been able to find the kind of sound that cuts through when needed. It is a bit pricey for an overdrive pedal, but compared to all of the other upgrades that a player may be making to their bass or amp, I would recommend trying this little powerhouse first.
Music background: 40 years and counting playing bass, guitar, keys, piano, and whatever else I can get my hands on.

Darkglass Reputation Upheld!

This was my first bass-specific pedal and it did not disappoint. I wanted a bit of drive and grit as an option, and this thing delivers that and more. The range of drive and distortion level ranges greatly from just a touch to pure insanity (and fun). The fact it doubles as a DI box too is great. My only complaint is the DC power input jack is not in an expected or ideal location, but with some right-angle cables, it's not a problem.
