Order before 3pm Mon-Fri for Next Day Delivery

Darkglass Electronics Microtubes 500, 500 Watt Handmade, Class D Bass Ampflier Head, with 2 classic Darkglass Distortion Circuits

The creation of the Microtubes 900 was executed with a single goal in mind: develop a no-nonsense bass amp with that distinctive Microtubes sound, an unparalleled flexibility, plenty of power, and a simple yet elegant design.

The resulting product far exceeded the expectations of even the most fastidious of bass players, and the M900 fast became the amplifier that professional bassists the world over would desire.

Massive Tone for the Masses

New for 2017, those genius designers at Darkglass Electronics have done it again, with the release of the Microtubes 500! This little brother to the M900 delivers a whopping 500 Watts RMS, features both the B3K and VMT distortion circuits (which can be activated via footswitch), is even more compact, and is a much more affordable option than it's larger sibling.

Despite only posessing 500 Watts of Class D power, the Microtubes 500 still manages to maintain the same tone and flexibility as it's predecessor, but is small and light enough to fit into your gig bag, or even on your pedalboard, making it even easier to transport. This powerful little amp is suited to all manner of musical genres and playstyles, with it's detailed 4-band EQ (with switchable mid-range) and superb distortion circuits, opening up the door to all manner of sonic possibilities.

Watch out for this amazing amplifier arriving at your local PMT store soon! If you have any queries regarding the availability of this amplifier, contact our online sales team directly.
