Critic Reviews

Darkglass Electronics Microtubes 900 Review - Premier Guitar

premierguitar.com

The Darkglass Microtubes 900 Bass Head impresses with its sleek design and powerful 900-watt output, delivering tones from crisp clarity to robust overdrive. Its versatile overdrive modes—B3K and VMT—offer distinct tonal palettes, enhancing its appeal. The smart EQ controls and Microtubes Engine add to its adaptability, making it a standout in the class-D amp market. However, its single speaker jack limits cabinet configurations, and it comes at a higher price point. Despite these drawbacks, its build quality and tonal versatility justify the cost for many bassists seeking a high-performance amp.

Best micro amp on the market.

From focused and clear to down and dirty - this head has never failed to deliver. Replaced my Mesa Boogie Subway 800+ with this head and have never turned back

My main bass amp

When I think about it, this is the main bass amp I use. It's got a really nasty distortion sound yet a nice jazz sound. Portable? Yes. Good sound? Yes. Would I recommend it? Yes.
