Blackstar #Bass U30
Blackstar · amplifier
The Blackstar Unity Bass U30 is a 30-watt 1x8-inch solid-state bass combo amplifier built for practice, rehearsal, and small venue use. It features three distinct voicings — Classic for vintage warmth with natural compression, Modern for clean articulation with extended low-end response, and Overdrive for gritty valve-like grind — alongside a three-band EQ with a semi-parametric mid control for precise tone shaping. Built-in compression and chorus effects increase punch and depth. At 30 watts through a custom 8-inch speaker it produces full, warm bass tone at manageable volumes suited to home practice and small performances.
