Description

The Microtubes X-900 is the 900W bass head developed by Darkglass that integrates the innovative X distortion system from the Finnish company, allowing separate control over saturation management and compression of high and low frequencies.

Designed based on the renowned X series pedals, this head sets a new standard for precision and control.

Featuring a 900-watt Class D amplifier and an ultra-quiet 6-band graphic equalizer that allows for tonal shaping from aggressive overdrives to crystal-clear cleans, to meet everyone's needs.

The X distortion circuit allows bassists to select exactly which frequencies to compress and saturate, for lows and highs respectively.

Equipped with MIDI for channel switching and mute, impulse response cabinet simulation, with up to three different virtual cabinets storable, auxiliary input, and headphone output, to offer unparalleled versatility and control.

A true musical travel companion.

Controls

Passive/Active: Use this push-button switch to toggle between passive and active mode.

X: Use this button to activate or deactivate the Microtubes X Engine.

Clean Comp: Use this push-button switch to activate the compression circuit for the clean channel.

Vol (Clean Comp): Sets the level of the clean channel when the compressor is activated.

HPF (High Pass Filter): Controls the cutoff frequency of the high-pass filter that is applied before the clean signal is sent to the distortion circuit to be distorted.

Drive: Sets the amount of distortion that is applied to the frequency range filtered by the high-pass filter.

Mix: Controls the blend between compressed lows and distorted highs.

LPF (Low Pass Filter): Controls the cutoff frequency of the low-pass filter that is applied before the clean signal is fed to the compression circuit to be remixed with the high-pass side.

Comp: Controls the amount of compression for the low band when X is activated.

Level: Sets the output volume of the X channel.

Low Shelf: +-12 dB at 80 Hz. 250 Hz / 500 Hz / 1.5 kHz / 3 kHz: +-12 dB.

High Shelf: +-12 dB at 35 kHz.

Master: Sets the overall volume of the unit.

Mute: Use this button to mute the amplifier.
