900 Watt bass amplifier with graphic EQ, Microtubes distortion and extensive connections, including footswitch

The Darkglass Electronics Microtubes 900 v2 is a revised version of the popular bass amplifier from Finland. Not only does it convince with the well-known versatile sound of highest quality, but also with an extensive connection periphery, which makes it the ideal bass amp for stage and recording studio. Accordingly, the amplifier in its elegant aluminium chassis offers a particularly variable analogue preamplifier, which, in addition to the clean section with 6-band EQ and compressor, also features a Microtubes engine with the overdrive voicings of the B3K and Microtubes vintage pedals. The 900 watt output of the Class D power amplifier promises ample volume reserves on the bass speakers, which can be connected via two combination sockets. Last but not least, the Darkglass Microtubes 900 v2 is equipped with pre- and post-DI outputs for direct acceptance, a headphone jack, a speaker simulation and a USB port.


To customize the sound, the Darkglass Microtubes 900 v2 offers not only a graphical 6-band EQ, but also the Microtubes engine for juicy overdrives and a compressor.

Variable clean section with 6-band graphic EQ

The heart of the redesigned Darkglass Microtubes 900 v2 is the particularly variable preamp in analog circuitry, which consists of a clean section and Microtubes Engine. The clean channel convinces with a particularly transparent reproduction, which brings the character of the used bass and the player unadulterated to hearing. At the same time, the 6-band graphic equalizer allows you to precisely adjust the character of the sound, while the integrated One Knob compressor provides a smooth, rich sound experience.

Overdrive thanks to Microtubes engine

The Microtubes Engine, connected before the Clean section, convinces with the voicings of the Darkglass Microtubes B3K and Microtubes Vintage effect pedals. After activation, a wide range of outstanding overdrive sounds is available, ranging from subtly breaking crunch to midrange vintage drive to brute distortion clubs for modern metal. In order to maintain definition and pressure in the low frequencies, the clean signal can be continuously mixed in.

Suitable for stage use with 900 Watt power amplifier

The Darkglass Microtubes 900 v2 Head is equipped with a powerful power plant in the form of a Class D amplifier for volume reserves suitable for the stage. In spite of the transport-friendly dimensions of the 2.9 kg weight, this delivers a full 900 watts of power, which make every note of the mark-shake sound in the pit of the stomach palpable and make the earth tremble. The Darkglass Microtubes Bass-Head is equipped with two combination sockets, which accept Speakon and jack plugs, so that the enormous power reaches the bass speaker safely.

Extensive connections and speaker simulation

The Darkglass Microtubes 900 v2 also proves to be the ideal sound center for live gigs and recording sessions with its extensive and innovative connection peripherals. In addition to the Pre-DI connector, which outputs the unprocessed input signal in balanced form, there is also a balanced Post-DI connector, which picks up the signal behind the sound shaping elements. There is also a headphone jack with its own volume control for silent bass playing. Another special feature is the integrated loudspeaker simulation based on Impulse Responses (IRs), which is available as a post-DI and headphone connection and guarantees a particularly natural sound experience even without a connected speaker. Last but not least, the Darkglass Microtubes 900 v2 makes contact with the Darkglass Software Suit via the USB port, which can be used to extensively adjust loudspeaker simulation and compressor.

DARKGLASS ELECTRONICS Microtubes 900 v2 Rückseite

The rear panel of the Darkglass Microtubes 900 v2 contains the extensive peripherals, including effect path, pre- and post-DI-outs, headphone jack, MIDI, speaker jacks and USB.

Intelligent Footswitch and MIDI

The Darkglass Microtubes 900 v2 also has a MIDI jack and a footswitch connector for control. Already included, the Darkglass Intelligent Footswitch enables the Microtubes Engine to be switched on and the bass amplifier to be muted with just one switch.
