OWNER’S MANUAL

2018 ended up as the most important year in Darkglass history. With groundbreaking new

products, renewed classic releases, and limited-edition pedals, our product catalog grew

stronger than ever and we took more steps in the direction we’ve always strive for: making

Developing new products is often a long and challenging process, full of surprises and

hard-learned lessons. We have learned and improved tremendously since the release of

our first amplifier, and now we have the pleasure of starting 2019 with a completely

redesigned version of our Microtubes 900. Boasting of enhanced durability, more flexible

equalizer, studio-grade compression, impulse response cabinet emulation, and even MIDI

control, the Microtubes 900 v2 features all the features and power the modern,

professional bassist needs in the same compact, gorgeous format.

the best gear for musicians all over the world.

DESCRIPTION

The Microtubes 900™ V2 is a 900W amplifier equipped
with an all analog preamplifier, Class D Power Module
and a digital impulse response cabinet emulator for DI
outputs or headphones.

Probably the first thing you will notice from the
Microtubes 900 is its unusual control layout: On the
right side you’ll find the clean section which is the
foundation of your sound.

It features Gain and Master volumes and active 6 band
EQ. Along with the mandatory Low and Treble controls
you will find 250Hz, 500Hz, 1.5KHz, 3KHz sliders.
Character is all in the midrange, by having 4 dedicated
Mid controls allow you to cover the whole mid range
(250Hz to 3kHz) you have total control and flexibility
over the amplifier’s character.

On the left side, by the Input jack you will find the
Microtubes® Engine which acts as an extra channel
that can bring your crisp clean sound to the next level
by helping you cut through any mix while adding
anything from subtle tube break up, harmonics and
natural compression to obliterating distortion.

The Microtubes Engine can be engaged via the front
panel or via our own digitally controlled ™ (jack on rear
panel). Besides engaging the Microtubes circuitry you
can hold the actuator to Mute the amplifier.

The Intelligent Footswitch is housed in an elegant,
laser engraved unibody chassis and requires a
standard ¼” mono cable (not included) for it’s full
operation.

Besides this incredible versatile preamplifier, we
equipped the power module with some unique control
over the power output and minimum speaker loads:

The standard mode will deliver 900W RMS at 4Ω/500W
at 8Ω. If you select the 2Ω Mode via the rear panel
switch the amplifier will deliver 900W at 2Ω/500W at 4
Ω and 350W at 8Ω .

This deceivingly simple feature allows for maximum
power adaptability: It doesn’t matter the cabinet
configuration or power requirements, the Microtubes
900 will deliver accordingly.

FEATURES

FRONT PANEL

INPUT : Use this jack to connect your instrument via a
standard ¼” 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 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 4 Band Active EQ for additional
tone shaping in addition to the Tone knob described below).
