YouTube video BassTheWorld.com · 2019-01 — Six Darkglass pedals, including the Microtubes B3K, played back to back.

Why it matters

The Microtubes B3K is the pedal that established Darkglass with bass players who wanted distortion without losing the bottom end of the signal. It sits mid-way through the company's pedal range in price, above the entry pedals and below the larger preamp units. Blending clean and driven signal is the feature that separates it from a generic distortion box, which is why it turns up on so many bass boards.

Note

THE modern bass overdrive — shaped a generation of prog-metal bass tone.
