Get to know them!

The Darkglass Electronics Microtubes 900 bass amplifier head delivers pristine tone with fast attack, while also allowing you to blend in any shade of overdrive or distortion you desire. You can engage the Microtubes Engine by either pushing the front-panel button or engaging the included footswitch for anything from a bit of grit to full meltdown. The Microtubes 900's clean section offers standard EQ controls along with switches for selecting your high- and low-mid frequencies. And the Microtubes 900 is also incredibly lightweight and portable, making it easy to gig with.

Clean section with powerful tone shaping

You'll find the Microtubes 900 bass amplifier head to be extremely versatile, whether utilizing the onboard grit or not. Its clean section gives you controls for treble, bass, high-mids, and low-mids. Two switches situated on the face of the unit define the mid frequencies that are affected. Whether looking for the warm tones of old-school thump, a scooped slap tone, or something that responds well to pick playing, the clean section of the Microtubes 900 will get you there.

Onboard Microtubes Engine

Darkglass Electronics's Microtubes preamps and overdrive pedals are extremely popular at Sweetwater for how well they retain your bass's core tone, while still allowing you to dial in any shade of grit you desire. Now you can get those same saturated tones out of this powerful, gig-ready amplifier. Simply bring the Microtubes circuit in with the button on the face of the unit. Or plug in the included Intelligent Footswitch for alternating between clean and drive on the fly.

Darkglass Intelligent Footswitch

This compact device allows you to utilize many of the Microtubes 900's tonal features from your pedalboard. A quick tap of the pedal brings the amplifier's overdrive circuit into and out of play. Hold the switch for three seconds, and you'll mute the amplifier's output. This is great for tuning or between sets. The Intelligent Footswitch uses a proprietary communication protocol and is the only pedal that will work with the Microtubes 900. It can be connected to the amplifier with a standard 1/4" instrument cable.

Convenient gigging amplifier

One of the greatest benefits of purchasing a Darkglass Microtubes 900 bass amplifier head is it's gig-friendly construction. You'll immediately notice its compact dimensions that will easily slip into your backpack. And the 900-watt power section is energized by a Class D design. This keeps the amplifier coming in at a very manageable 6.39 lbs. Finally, the Microtubes 900's understated lines are courtesy of a durable aluminum chassis that protects the amp while on the road.
