Uncompromised Precision and Utmost Control - The Darkglass Microtube X900 Bass Amplifier Head

A quest tackled relentlessly, and meticulously crafted with the target of achieving exceptional power with unprecedented precision - without concessions or shortcuts. Darkglass is proud to introduce the groundbreaking X900 amp.

Designed after the revered Xseries pedals, this amplifier sets a new standard for accuracy and control, packed with a Class D 900-watt amplifier and an ultra-quiet 6-band graphic equalizer that can sculpt the tone from aggressive and overdriven to crystal clear clean to suit everyone’s needs. The X distortion circuit allows users to select exactly what frequencies they want to compress and saturate for the low and treble, respectively. It also features MIDI for channel switching, and muting programmability, impulse response, cabinet simulation, with up to three different storable virtual cabinets, auxiliary input, and headphone output, offering unmatched versatility and control. It's a true companion for musical touring.
