The new face of bass

Unity Pro Bass are the result of countless hours of technical research and benchmarking against the most iconic historic references. Designed from the ground up by bass players, for bass players they are straight forward and powerful. Blackstar’s unique Response control allows the player to choose between the sound and feel of three classic power amp stages, shaping compression, natural drive and dynamics.

Combined with three distinct preamp voicings and a 3-band semi-parametric EQ, Unity produces infinitely flexible bass tone and exceptional feel, whatever your playing style.

Any player, any sound

Performance optimised, powerful. Unity’s deceptively simple controls allow you to quickly and easily mould and create your tone no matter the style.

The sound in your head

Offering Classic, Modern and Flat voicings, Unity bass is perfect for playing any style. Classic offers a Valve-Inspired growl with a Vintage EQ, Modern offers High-headroom dynamics and advanced EQ and Flat provides totally flat signal that's clean and transparent.

Unique response control

Unity’s unique response control adapts 3 power amp stages to shape compression and feel. Linear response is powerful and articulate, 6L6 packs the compression and punch of 6L6 power valves and 6550 creates the dynamics and headroom of high power 6550’s.

Overdrive options

Adding to Unity's array of features, the amp comes with 3 different overdrives all with a user-controlled blend. Overdrive offers smooth, open and harmonically rich tone. Distortion provides balanced, pedal-like power and Fuzz creates an in-your-face classic bass fuzz.
