PROS
- • Markbass’s signature Art Tube voicing delivers a surprisingly warm, tube-like character.
- • The 12” speaker offers a balanced frequency response, avoiding excessive boominess common in smaller cabs.
- • The EQ section, with its unique mid-low and mid-high controls, allows for precise tone shaping.
- • The integrated XLR DI output provides a clean, usable signal for recording or live sound reinforcement.
CONS
- • The lightweight construction, while convenient, might feel slightly less robust than heavier, all-steel amps.
- • 150 watts is adequate for smaller gigs, but power users will likely want more headroom.
- • The auxiliary input lacks a level control, potentially causing volume imbalances.
