900-W Bass Amplifier

Absolute Control:

- With enhanced durability, improved equalizer, studio-grade compression, impulse response cabinet emulation, and MIDI control, the Microtubes 900 v2 features all the options the modern, professional bassist needs in a compact, sleek, and loud format.

Darkglass Suite:

- Using the desktop version of the Darkglass Suite allows you to select 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 900 v2. 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.

Controls:

- 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 to distort early (feel free to use if such additional distortion is desired).

- Microtubes: Use this push-button to turn on or off the Microtubes Engine to add natural compression, organic harmonic enhancement, and saturation ranging from mild overdrive to high-gain bass rage. The Microtubes Engine operates before the clean section (you can therefore use the 6-Band Active EQ for additional tone shaping in addition to the Tone knob described below).

- Compression: This knob controls the amount of dynamic compression added to the Microtubes Engine. The make-up gain is adjusted automatically. The compression can be turn off or assigned using the Darkglass Suite.

- Drive: This knob controls the amount of distortion that the Microtubes Engine will deliver. It will change from a soft warm overdrive to a massive modern distortion sound.

- Tone: This knob controls the high harmonic content of the Microtubes Engine via a variable low-pass filter: crank it up for additional attack and definition or dim it down for a smoother sound, especially handy if already running bright clean EQ setting or cabinets with tweeters.

- Level: Use this knob to control Microtubes Engine’s output volume.

- Blend: Use this knob to mix between the clean signal and the distortion signal (Microtubes Engine).

- B3K/VMT: This push-button switch selects between two overdrive voicings: B3K mode will deliver an aggressive, percussive sound, while the VMT will bring up the mids for a warmer, more neutral character.

- Gain: Use this knob to change the volume of the signal before the Active 6-Band EQ. You can set it low for ensuring the cleanest operation possible or set it higher for more aggressive growl.

- Bass: +-12 dB at 80 Hz. Use this knob to change the low content of the signal.

- Mids: +-12 dB at 250 Hz, 500 Hz, 1.5 kHz and 3 kHz. This graphic EQ controls the mid content of the signal.

- Treble: +-12 dB at 5 kHz. Use this knob to change the high content of the signal.

- Master: Use this knob to control the overall volume of the amplifier.

- Mute: Use this push-button to mute the amplifier.
