Built for Tonal Flexibility

The Blackstar Unity Bass U120 bass combo amplifier was built for tonal flexibility. Choose between three distinct preamp voicings, and then sculpt the result with a 3-band EQ. Increase your bass's punch and depth with compression and chorus effects. The U120 is loaded with enough connectivity for live, studio, and home use. And if you want to beef up your output onstage, you can add a Unity U250ACT powered cabinet for an extra 250 watts of power. Get the eminently versatile Unity Bass U120, and everything from valve grind to high-headroom clean will be within your grasp.

Everything from valve grind to high-headroom clean

Whatever sound is in your head, you can coax it from the Unity Bass U120. 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 U120 features built-in compression and chorus effects.

Loaded with useful features for stage and studio

The Blackstar Unity Bass U120 is packed to the gills with useful features. Connectivity abounds, with an XLR + 1/4" line output with independent level control. A -10dB pad accommodates both active and passive instruments. And an MP3/line input is onboard to supercharge your practice sessions. The bassists here at Sweetwater are especially impressed by the U120's integrated link for Blackstar's Unity U250ACT powered cabinet, which allows you to add an extra 250 watts of power to your rig.

Reviews

WOW! Packs a punch!
I've been a professional musician since 1977, performing on stages across the country for decades and I've never used a bass amp this small with so much punch, clarity, and volume. Those clever British engineers have developed one of the best compact bass guitar amplifiers in the world and I can highly recommend the Blackstar U120 as an outstanding compact bass combo amplifier. It fits into the trunk of m car but can fill the stage with a robust sound. If you need more power for larger venues, simply add the self powered expansion cabinet(s) (250 extra watts - 1x15) and you're good to go. It's simply amazing.
