Everything from valve grind to high-headroom clean

Whatever sound is in your head, you can coax it from the Unity Bass U30. It all starts with three distinct preamp voicings: Classic, Modern, and Overdrive. Beyond that, a 3-band EQ with a semi-parametric Mid knob supplies you with plenty of sound-sculpting power. Need more punch and depth? No problem. The U30 features built-in compression and chorus effects.

Loaded with useful features for stage and studio

The Blackstar Unity Bass U30 is packed to the gills with useful features. Connectivity abounds, with an XLR + 1/4" line output with independent level control.
