Blackstar Unity Bass U30
Blackstar · amplifier
The Blackstar Unity Bass U30 is a 30-watt 1x8-inch solid-state bass combo amplifier built for home practice, studio recording, and small venue use. Three distinct preamp voices — Classic for vintage warmth with natural compression, Modern for clean articulation with extended low-end response, and Overdrive for gritty valve-like grind — give it tonal flexibility beyond a single-voice practice amp. A three-band EQ with semi-parametric mid control enables 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 in a compact and portable package.
