Add to Cart
Three years ago Darkglass Electronics released it’s first amplifier, the Microtubes 900. Its unusual features, and design embodied the Darkglass ethos like none of our previous products. It was an uncompromising amplifier, incredibly versatile, and unapologetically loud. Now, a thousand days after the first Microtubes 900 saw the light of day, we are proud to announce the next step in its evolution, the Microtubes 900 v2.

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.

Well-equipped for direct recording and performance

While it does offer an impressive 900 watts to push some serious air through a speaker cabinet, the Darkglass Microtubes v2 amp head has everything you need for outstanding direct tones too. It has memory for up to three IR cabinet sims, and you can upload your own via USB. You also have your choice of pre- and post-processing DI outputs, allowing you to choose how much the Microtubes v2 shapes your tone.

Ample connectivity options for any type of bass rig

The Darkglass Microtubes v2 has the flexibility you need to integrate with practically any bass rig. Dual speaker outputs offer 1/4″ or speakON connectivity. A send/return loop makes it easy to integrate pedals and other effects processors. You can even optimize the Microtubes v2’s performance for any type of bass pickups, thanks to its passive/active input mode selector.

Your ideal practice companion

Whether you’re waiting backstage before a performance or waiting for your turn in the studio, Sweetwater knows it pays to stay warmed up on your instrument. The Microtubes v2 features an 1/8″ aux input for your smartphone, and a headphone output with its own volume control. Even with your rig fully set up, you can set up a private practice session to work on lines or simply jam along with your favorite tracks.
