Crisp, transparent and full sounding clean channel with gain, master and 4 band eq plus 3-way switches for both mid controls give you total control of your sound


More that just an overdrive: the proprietary, fully footswitchable, award winning circuitry adds more  that just saturation, it also excites harmonics and natural compression for a deeper, punchier more present sound. The combination with the flexible clean channel result in unprecedented sonic possibilities.

Clean channel: An versatile foundation for your tone. Gain and master controls, an active 4 band eq with low and high mids each with their own 3 way switch

Microtubes engine: bring your clean tone to the next level by helping you cut through the mix while adding anything from subtle tube break up, harmonics and natural compression to obliterating distortion

New limited edition Medusa Model

Darkglass Electronics launched their first amp the critically acclaimed Microtubes 900 in 2016.

However, creating limited run and special editions has become a cool tradition at Darkglass, so for 2018 the brand wanted to have something truly special, which is why they have collaborated with Christopher Lovell on producing the Microtubes 900 : Limited Edition in an all new and stunning black finish.

This amazing artist has become a true Instagram sensation as of late with some of the most epic, dark artwork that has been seen in the past few years. He is also an excellent metal guitarist and loved the idea of having his artwork featured in the meanest sounding bass amplifier in production. The Microtubes 900 lends itself beautifully to a limited edition as the whole top lid could be used

Front Panel Features


Connect your instrument via a standard ¼” mono cable.


Switch from passive to active mode. Some active basses can have a hotter signal output which can make the amp distort early (feel free to use it on Passive move even with active basses if such additional distortion is desired).


Turns 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 4 Band Active EQ for additional tone shaping in addition to the Tone knob described below).


Controls the amount of distortion that the Microtubes Engine will deliver. It will change from a soft warm overdrive to a massive modern distorted tone.


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. This is handy if running bright clean EQ settings or cabinets with tweeters.


Controls the Microtubes Engine’s output volume.


Mixes between the Clean signal and the Distortion signal (Microtubes Engine).


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.


Changes the volume of the signal the Active 4 Band EQ. You can set it low prior to ensuring the cleanest operation possible or set it higher for more aggressive growl.


+-12dB at 80Hz. Changes the low content of the signal.

Low Mids

+-12dB of the selected frequency via the LOW MIDS ƒ switch (described below). Changes the lower mid content of the signal.

Low Mids ƒ

Use this switch to change the frequency of the low mid band from 250Hz, 500Hz or 1kHZ.

Hi Mids

+-12dB of the selected frequency via the HI MIDS ƒ switch (described below). Changes the higher mid content of the signal.

Hi Mids ƒ

Use this switch to change the frequency of the hi mid band from 750Hz, 1.5kHz and 3kHZ.


+-12dB at 5kHz. Changes the high content of the signal.


Controls the overall volume of the amplifier.


Mutes the amplifier.

Back Panel Features

Speaker Output

Connects the amplifier to your cabinet. This Speakon combo jack allows for either Speakon or ¼” speaker cable operation.
*WARNING: Do not use an instrument cable with this jack. Using an instrument cable can damage your amplifier.


Press when using a 2Ω load. You can use this control to lower the output if your 4Ω cabinet is not able to handle more than 500W (you can also get 350W with an 8Ω cabinet in this configuration).

Pre Amp Out

This output connects the preamp to a different power amp.

Power Amp In

Use this input to connect a different preamp to the power amp. (master volume will be disabled)


Selects what signal will be delivered by the DI output. Selecting PRE, sends a clean copy of your input bass signal. Selecting POST delivers a signal processed by the preamp of the amp (gain, distortion, eq, master, etc.)

Ground Lift

Lifts the ground of the DI XLR output. If a ground noise in you DI signal is experienced, try changing the setting of this control.

Balanced Output

Connects the Microtubes 900™ preamplifier to balanced equipment (mic preamp, console, recorder, compressor, audio interface, etc.) via a standard XLR jack.


The Footswitch allows you to remotely engage and disengage the Microtubes Engine. Hold the footswitch to Mute the amplifier. The VMT/B3K push button will remain operational with the Intelligent Footswitch plugged in.
* Use a regular mono instrument cable to connect the amplifier to the footswitch.
* Remove the cable from the footswitch jack in the rear panel if you want to control the amp from the front panel.
