Is This the Most Versatile Bass Preamp Ever?

The Darkglass Alpha·Omega Ultra might be one of the most versatile bass preamps ever. At its core are two discrete distortion circuits that allow you to explore exciting tonal frontiers while reveling in boundless dynamic range. Sculpt fresh sonic textures with a 6-band active graphic EQ. Then pipe everything through a single-user digital impulse-response cabinet emulation. You're in complete command with Bypass and Distortion footswitches that allow separate use of the Alpha·Omega Ultra's distortion and EQ. And thanks to its 1/8-inch Aux input, this is the perfect solution for practicing along with guide tracks from your mobile device or computer. The Alpha·Omega Ultra also includes a headphone output, switchable ground lift, and a Micro-USB B port for loading new virtual cabinets from your Mac or PC.

Take studio-grade cabinet emulations everywhere you go

The right speaker cabinet can lend a massive, natural tone to your bass. But capturing that sound is easier said than done. Not only do you need a well-tuned cabinet, but you also need a great-sounding room and an expensive microphone. And if you're trying not to disturb the neighbors, that's a whole different issue. But thanks to the Alpha·Omega Ultra's digital impulse-response cabinet emulation, you have a complete array of top-of-the-line cabs at your disposal. Built directly into the Alpha·Omega Ultra's XLR output, this studio-grade effect will inject your rig with uncompromising, ready-to-mix bass tones. And loading up a new cabinet is easy — just plug into your Mac or PC via the Alpha·Omega Ultra's Micro-USB B port. The cab simulation is also integrated into the pedal's headphone output, a feature that the bassists at Sweetwater use to turbocharge their silent practice sessions.

(for Older Model) This is pedal I do not want to ever be without.

I am a bassist with a pedal addiction...I know I know, bad bassist...but I truly can say, no pedal I have ever had is as ideal as the darkglass AO Ultra. As a DI it is perfect, as a distortion/overdrive it is ideal, as an EQ it hits the points I need. Now before I get pegged as a metal bassist, I am a worship bassist, who plays a NS Design Omni (fretless EUB) and uses a bow often. The tone I can dial in is absolutely amazing. The amp/cabinet simulation is just beautiful. This is where my only complaint is, the simulation, which you can change with your computer, it is in the headphones and DI only, not the 1/4 out. My solution was to use a XLR to 1/4" so my amp can have the extra warmth. Mine is the older model, and I ordered it two days before the new model was announced. I am completely impressed by darkglass, they make some of the best products around. Special thanks to Nick Beach at Sweetwater!

Great sound modeling and best distortion on the market

You just can't go wrong with Darkglass. This is the one pedal on my board that is just always on
Let's you cut through the mix easily without dominating.

Tone Variety for Days!

Hours. Hours of my life gone just messing with this thing. It's great. The tonal options (even without the distortion) are vast. The Direct Out is awesome; the cab sim is pretty great; the 6-band EQ is fantastic. My only complaint (and it's a big one) is that, in order to use other effects after the distortion in the signal chain, you can't use the Direct Out. That's a problem if you like a little modulation or time effects on occasion for some flavor in a live setting without an amp. I attempted to run a couple effects before the distortion in the signal chain and, as I expected, it sounded terrible. I really wish this had something that would function as an effects loop, or at least allow effects between the distortion and the Direct Out. If that's not something you're concerned about, and you just want some killer distortion tones, this has got you covered.

Sounds great, BUT...

Love this pedal and the way it sounds, but the power input is designed very poorly. Every time you plug in, theres a loose feel to it. Once it broke while on stage i had to stop my set and try to find the problem on my pedalboard. Noticed this pedal was the problem, opened it and found a serious design flaw with the power jack hanging off of the board. I have my technician moddifying it now so i dont get any more surprises, but for the money, this pedal isnt built properly

cab sim hiss

great sounding but you'll get hell from soundmen using it as a di due to a hiss that is present in all of the cab sims. I've used it for over a year and really like it but am going to have to sell it soon due to the inescapable hiss.
