The Dual-Voiced Powerhouse of Modern Bass Distortion Before the Alpha·Omega Ultra, Darkglass had already cemented its reputation as the go-to brand for forward-thinking bass distortion. The Microtubes B3K and B7K brought clarity and aggression to the bass world, redefining what overdrive could mean for low frequencies. But by 2017, founder Douglas Castro and his team set their sights on expanding beyond that “tight and glassy” Microtubes character. They envisioned a new kind of drive — fatter, rawer, and darker, but still articulate. Enter Jon Stockman of Karnivool, whose input helped shape the original Alpha·Omega pedal. Designed with two blendable distortion paths — Alpha (aggressive and punchy) and Omega (raw and brutal) — the pedal introduced a more saturated, muscular take on Darkglass’s aesthetic. It wasn’t just about clarity anymore — it was about force, depth, and sonic authority. The Alpha·Omega Ultra builds on this, incorporating a six-band graphic EQ, impulse response (IR) cabinet simulation, headphone out and USB connectivity, expanded routing options, and a refined, rack-quality preamp section. It’s not just a distortion pedal — it’s a full-featured tone hub. The Core Sound: Two Distortion Engines, One Vision At the heart of the Alpha·Omega Ultra is its dual-path distortion engine: Alpha engine: Tight, mid-forward, slightly compressed. Great for articulation, pick-style playing, and cutting through dense mixes.Omega engine: Fatter, darker, and gnarlier — perfect for huge, wooly tones and down-tuned basses. You blend between these two characters using the Mod knob, which is not just a gimmick — it lets you fine-tune the nature of the drive to match your instrument and musical style. It’s a spectrum, not a switch, which means you can live in-between: Alpha for the edge, Omega for the weight. Add to that: These features alone make it extremely powerful, but what elevates the Ultra model is what lies beneath. The “Ultra” Difference: Studio-Grade Control and Connectivity Six-Band Graphic EQ The onboard graphic EQ lets you precisely sculpt your tone with center frequencies at 80 Hz, 250 Hz, 500 Hz, 1.5 kHz, 3 kHz, and 5 kHz. This is not a simple tone knob or a basic 3-band layout — it’s surgical. You can scoop, push, or flatten your mids and highs to fit whatever room, mix, or rig you’re playing through. This EQ is post-drive, meaning it shapes the final sound you’re sending to your cab, DI, or front-of-house — and that makes it incredibly practical on stage or in a studio setting. Cab Sim and IR Loader One of the defining features of the Ultra series is IR-based cabinet simulation. The Alpha·Omega Ultra allows you to: This makes it a perfect standalone DI box — no amp required, no compromise. Whether you’re recording direct at home, running into an in-ear monitor setup, or flying to a gig where you need to go straight to FOH, it’s plug-and-play. USB and Software Integration Through USB, you can: It’s not a deep editor like some modelers, but it’s a user-friendly interface for quick personalization. On Bass: Brutality with Definition Plug a 5-string into the Alpha·Omega Ultra, and you immediately understand the appeal. This is modern distortion for modern bass — aggressive but not messy, huge but controllable. Key tonal identities include: Crucially, the pedal always respects your playing technique. It doesn’t flatten or obscure your dynamics, which is a big reason why it appeals to such a wide range of players — even those who don’t consider themselves distortion-heavy artists. It also plays well with compressors, modulation, and fuzz, especially when placed early in the chain. Pros and Cons Pros: Cons: Conclusion: The Alpha·Omega Ultra is a Full Bass Rig in a Box For players who want a distortion preamp with real-world versatility, the Darkglass Alpha·Omega Ultra delivers in every respect. It can be your amp substitute, studio channel, pedalboard anchor, or just your favorite distortion — and in all cases, it will do the job with authority and definition. What separates this from many other options isn’t just tone — it’s control and flexibility. With cab sim, EQ, DI, headphone monitoring, and drive shaping, this is a pedal that can live at the center of your rig and adapt to whatever situation you throw at it. It represents the next step in Darkglass’s evolution of modern bass tone — a pedal built not just for one sound, but for the complex and varied needs of contemporary bassists. Whether you’re on stage, in the studio, or practicing at home, the Alpha·Omega Ultra is an intelligent, aggressive, and refined companion.

A Decade of Defining Modern Bass Tone Few bass pedals in the past 20 years have had the impact and staying power of the Darkglass Microtubes B7K. First released in the early 2010s by Finnish company Darkglass Electronics, the B7K (and its simpler sibling, the B3K) quickly became a cornerstone of modern bass sound, especially in genres like metal, progressive rock, djent, and fusion, but also in session, pop, and electronic music. At its core, the B7K is a preamp/overdrive pedal that blends clear, aggressive distortion with a powerful EQ section, making it equally suited for clean tone shaping and harmonically rich grit. But what really made it a game changer was its ability to maintain articulation and clarity under gain — a feat few bass drives had managed without sacrificing low-end or note definition. A Bit of History: The Rise of Darkglass Founded by Douglas Castro in Helsinki in 2009, Darkglass emerged from a desire to build gear that could keep up with the demands of modern, technically complex music. At the time, most bass drives either lacked definition, lost bottom-end, or felt like adapted guitar circuits. Castro’s designs aimed to change that — and the B7K was the breakout product. The B7K didn’t just offer distortion; it sculpted the tone of modern bass. It became a staple for touring professionals, bedroom producers, and recording engineers alike. Whether it was Nolly Getgood, Adam “Nolly” Getgood of Periphery, or countless players in the extended-range and multi-genre scenes, the B7K became synonymous with tight, mix-ready bass tone. Features and Layout: The Power of Precision The Microtubes B7K is both an overdrive and a preamp, featuring: The clean architecture and modular layout make the B7K extremely adaptable — it works equally well on pedalboards, in DAW environments, or as a preamp driving a power amp or interface. Sound: Clarity Under Fire The core appeal of the B7K lies in its precise and articulate gain structure. Where many bass overdrives mush out or lose clarity, the B7K delivers tight, punchy, mid-forward grit that remains focused even with extended-range basses or fast playing. Key sonic characteristics: While it shines in modern, aggressive settings, many players use it purely as an EQ/preamp, with minimal drive, for shaping live tone or adding sheen to studio DI tracks. Why It Mattered — and Still Does Before the B7K, the bass overdrive landscape was fractured. Players often had to choose between: The B7K solved this by offering studio-level tone sculpting in a pedal format, with enough gain for extreme players but enough transparency and flexibility for clean users. It bridged the gap between DI box, preamp, and distortion, becoming an all-in-one solution that was easy to trust on stage or in the studio. And crucially, it helped usher in a new aesthetic of bass tone — forward, punchy, hi-fi, but with muscle. Applications: More Than Just Metal Though often associated with heavy genres, the B7K is a chameleon: It also integrates seamlessly with compressors, modulation, fuzz, and even IR loaders or amp sims. Pros and Cons Pros: Cons: Conclusion: A Modern Classic, Deservedly So The Darkglass Microtubes B7K has earned its place in the pantheon of essential bass pedals. It’s not a flavor-of-the-month — it’s a true sonic tool, capable of everything from subtle enhancement to outright overdrive savagery, and always with a level of control that few other pedals offer. For players who want to sound tight, modern, mix-ready, and defined, the B7K still reigns as one of the best options available. And for those who appreciate the value of a preamp that doubles as a studio channel strip, it’s arguably unmatched at its price point. It changed the conversation about bass tone — and for many players, it still sets the standard.
