Darkglass Microtubes X 900 Bass Amplifier Head - Black

Darkglass Microtubes X 900

For bassists who demand uncompromising power and surgical tonal precision, the Darkglass Microtubes X 900 is a revelation in modern amplification. While this head is built on a lightweight, 900-watt Class D solid-state architecture, it completely reimagines the concept of harmonic saturation. Instead of using traditional glass tubes, which can be fragile and inconsistent, this amplifier utilizes the proprietary Microtubes X engine. This all-analog circuitry emulates the organic breakup and rich overtones of high-gain tube amps but adds a layer of modern versatility: it splits your signal into two variable bands. The high frequencies are sent to the distortion circuit for cut and clarity, while the low frequencies pass through clean and compressed, ensuring your foundation remains massive and defined.

The result is a tone that is incredibly tight and aggressive without ever losing the bottom end—a common issue with standard tube distortion. The construction is sleek and road-ready, housing a studio-grade VCA compressor and an ultra-quiet 6-band graphic equalizer that allows you to sculpt every nuance of your sound. Whether you are looking for a crystal-clear clean tone with immense headroom or a crushing, modern metal distortion, the X 900 delivers it with ease. Paired with the Darkglass Suite, you can load unmatched cabinet impulse responses (IRs) and configure your footswitch, making this one of the most flexible tools in a bassist's arsenal.
