Featuring all the options expected by modern professional bassists, the Microtubes 900v2 from Darkglass Electronics is a 900W amplifier head sporting the potent Microtubes B3K Engine. Capable of delivering everything from soft and warm overdrive to massive modern distortion for a range of applications, the Microtubes 900v2 is an excellent choice for studio or stage.

Front-panel controls include active 6-band EQ, a Drive knob for controlling the distortion level, and a Blend knob for balancing clean and distorted signals. You can select between two overdrive voicings: B3K for aggressive, punchy bass, or VMT for a more neutral, vintage tone with warmer mids. Further controls include compression (assignable to clean, B3K, or VMT tones), Tone for adjusting a variable low-pass filter, and switchable Active or Passive modes. I/O includes a pair of 2- or 4-ohm speakON speaker outputs, a headphone output for silent practice, an FX loop, an aux input for playing along with or amplifying your favorite tracks, a 5-pin DIN MIDI input, a footswitch input, and pre- and post-DI XLR outputs for DI applications, with three selectable cabinet emulations.

With the dedicated push button, you can 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, allowing you to use the 6-band active EQ for additional tone shaping.

With special push-button switches, you can change from passive to active mode. If your bass is active it can produce a hotter signal making the amp distort earlier.

Using the desktop version of the Darkglass Suite allows you to select and use any of our available impulse responses from the 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. Just connect to your computer via USB-C and tweak your amp head to your heart's content.

The compression 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 for each mode separately (Clean, B3K, and VMT).

The Tone 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, which is especially handy if you're already running a bright clean EQ setting or cabinets with tweeters.

• Bass: ±12 dB at 80 Hz
• Mids control of ±12 dB at 250 and 500 Hz, as well as 1.5 and 3 kHz
• Treble: ±12 dB at 5 kHz

The Intelligent Footswitch (sold separately) is an intuitive yet versatile accessory for your Microtubes 900v2. One tap will engage or disengage the distortion, while holding for 3 seconds will mute the amplifier. It's connected to the head via a standard 1/4" cable and is powered by a microcontroller that sends commands to the head using a proprietary communication protocol.
