Darkglass Microtubes X 900 – Review

The Darkglass Microtubes X 900 is a powerhouse bass amplifier head that combines pristine clean tones with crushing distortion in a sleek, portable package. Based on the popular Microtubes X distortion circuit, it offers exceptional tonal flexibility for both modern metal and more classic rock styles.

With 900 watts of power, it’s designed to handle the biggest stages without losing definition. The X distortion circuit splits your signal into low and high frequency bands, allowing independent control for a tight, controlled low end and aggressive high gain bite. This keeps your tone punchy and articulate, even in dense mixes.

The amp also includes cabinet simulation, MIDI control, and a flexible EQ section, making it an all-in-one rig for both live and studio use. Its lightweight design and intuitive interface mean you get professional-grade performance without back-breaking weight.

Pros:

• Massive 900W output with headroom for any stage

• X distortion circuit offers unmatched clarity in high-gain tones

• Cabinet sim and MIDI expand versatility

• Lightweight and portable

Cons:

• Premium price point

• Distortion voicing leans towards modern/metal tones, which may not suit all genres

Verdict:
The Microtubes X 900 is a beast for bassists who want power, clarity, and a distinctive high-gain voice in a compact amp head. If you play aggressive styles and want to cut through any mix, it’s hard to beat.
