Blackstar Unity 250W bass guitar amplifier

Introducing the Blackstar Unity bass guitar amplifier

These Blackstar Unity amps are perfect for players of any style. Whether you’re out gigging, travelling, or practicing at home, these compact amps will fit right in. Designed by bass players, for bass players, these pro amps have been built from the ground up, utilising the latest technical research and benchmarking against some of the world’s most iconic models.

Blackstar’s unique response control allows players to choose between three classic power amp stages: shaping compression, natural drive, and dynamics. Combined with three distinct preamp voicings and a 3-band semi-parametric EQ, these powerful amps produce infinitely flexible bass tones along with an exceptional feel. Plus, they're built inside a lightweight, durable, and compact casing, meaning that these impressively punchy amps can be transported to stages and live events without any hassle.

There's also 30-120W amps available, giving musicians on a budget a high quality amp that's within their price range.

Suitable for any style

Performance-optimised and featuring simple and responsive controls, Unity allows musicians to quickly and easily create expressive sounds, with the choice between three unique voices to let bass players shape their music exactly the way they want to. 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.

Perfect your performance

Push your music to the next level with Unity’s built-in Chorus, Compression, and Octave effects, and sound your best when you’re performing either in the studio or on the stage, thanks to the balanced XLR and USB connectivity.

Professional, powerful, and versatile

Unity’s unique response control adapts three 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. Adding to Unity's array of features, the amp comes with three 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.
