Darkglass Microtubes v2 and Alpha Omega 900 review | MusicRadar

musicradar.com

Darkglass has hit the mark with the Alpha Omega 900 and Microtubes v2, which boast a premium design and extensive tonal options suited for any bassist. The innovative distortion engine offers a perfect blend of punch and aggression, making it ideal for genres ranging from metal to jazz. However, the price tag is steep, and while the features are impressive, it may turn away budget-conscious players. Overall, these amplifiers deliver high-quality performance but require an investment that may not suit every musician's needs.
