Darkglass Electronics introduces Microtubes X 900, a 900W Bass Amplifier. Designed after the revered X series pedals, the Microtubes X 900 sets a new standard for accuracy and control. We packed an all-analog preamp, a 900 watt Class D amplifier, and an ultra-quiet 6-band graphic equalizer inside to sculpt tomes from crystal clear to aggressive and overdriven.
Using the desktop version of the Darkglass Suite allows you to suggest and use any of our available impulse responses from our provided library in addition to loading your own custom impulse responses. In addition, you can control the amplifier channel settings for the Super Intelligent Footswitch.
The intelligent Footswitch is an intuitive yet versatile accessory for your Microtubes X 900. One tap will engage and disengage the Distortion, while holding for 3 seconds will Mute the amplifier. It is connected to the head via a standard 1/4” cable and it’s powered by a microcontroller that sends commands to the head using a proprietary communication protocol.
Front Panel Features
Input: Use this jack to connect your instrument via a standard 1/4” mono cable.
Passive/Active: Use this push-button switch to change from passive to active mode. If your bass is active it can have a hotter signal, making the amp distort earlier (feel free to use if such additional distortion is desired).
X: Use this push-button to turn on or off the Microtubes X Engine which allows you to compress and distort your bass signal in two separate bands, solidifying the clean low end and distorting the highs to taste from articulate to aggressive. The Microtubes X Engine operates before the EQ section.
Clean Comp: Use this push-button switch to activate the compressor circuit for the clean channel.
Vol (Clean Comp): Sets the level of the clean channel when the compressor is engaged.
HPF (High Pass Filter): Controls the cutoff frequency of the high pass filter which is applied before the clean signal is fed to the distortion circuit. Ranging from 100 Hz (for thicker, fuzzier saturation) to 1 kHz (for ultra-sharp definition).
Drive: Sets the amount of distortion for the high pass side.
Mix: Controls the blend between the compressed lows and the distorted highs.
LPF (Low Pass Filter): Controls the cut-off frequency of the low pass filter which is applied before the clean signal is fed to the compression circuit. Ranging from 50 Hz (for only sub-bass) to 500 Hz (to preserve some clean mids).
Comp: Controls the amount of compression for the low band when X is activated. Both threshold and makeup gain are controlled to maintain a constant level. This control is also used to control the amount of compression when the compressor is enabled for the clean signal. The clean comp is full-range.
Level: Sets the output volume of the X channel.
Bass: +-12 dB @ 80 Hz.
Mids: +-12 dB at 250, 500, 1.5k and 3kHz.
Treble: +- 12 dB @ 3kHz
