DARKGLASS MICROTUBES B7K ULTRA V2 AUX DISTORSION

A Modern Bass Tone Icon: The Microtubes DNA in Ultra Version

The Microtubes B7K Ultra follows the lineage of Darkglass pedals that have become standards for bassists seeking precision, attack, and definition. The concept is clear: a modern, edgy, and articulate saturation designed to remain clear even with high gain. This "Ultra V2 Aux" version takes the concept further with a performance- and practicality-oriented approach, thanks to cab simulation, DI connectivity, and headphone/AUX functions for playing without an amp.

For Whom, Which Styles, and In What Contexts?

This bass preamp and distortion pedal targets intermediate to professional bassists who want a solid, sculpted sound ready for the stage. It excels in rock, metal, punk, hardcore, prog, but also delivers controlled warmth in pop, funk, or electro when Blend and Drive are finely adjusted. On a pedalboard, it can serve as the "main sound" (always on) or as a switchable saturated channel. In the studio, the DI output and cab sim facilitate clean, fast, and consistent direct recordings.

Controls, Settings, and Connectivity: A True Command Center

The Microtubes B7K Ultra V2 Aux combines a powerful preamp, an independent saturation section, and a very musical equalizer. The Drive, Blend, and Level controls allow precise adjustment of gain amount and the mix between clean and saturated signals, while Master manages the overall level. For tone shaping, the 4-band EQ (Bass, Lo Mids, Hi Mids, Treble) offers a wide range of action, with selectable mid frequencies to adapt the pedal to your instrument, tuning, and mix. The Attack and Grunt switches refine the saturation character (more attack and presence, or more low-end body). Practically, the headphone output and AUX input turn the pedal into a silent practice station, and the balanced XLR output with Ground Lift and Cab Sim meets the demands of both stages and studios.

The Sound

The Darkglass signature is present: a bass distortion that is tight, precise, and very clear, with a firm low end and a high-midrange that cuts perfectly through a dense mix. Dynamics are a strong point: by adjusting the instrument volume and attack intensity, you can go from a slight "grit" to a more aggressive saturation while retaining note detail. The Blend control is crucial to keep the clean foundation and add just the right amount of bite. This modern approach has won over many musicians on stage and in production, including Adam "Nolly" Getgood, Tyler Joseph, and Franz Lyons, known for present and defined bass tones.
