About Blackstar Unity U250

You can experience the new era of bass amplification with the Unity U250 250W 1x 15" Bass Combo Amplifier. This innovative product is the culmination of extensive technical research, benchmarking against iconic historical references, and is designed from the ground up by bass players, for bass players. The Unity U250 is not just an amplifier, it's a comprehensive tool for shaping your bass tone.

The Blackstar's unique Response control in this amplifier allows you to choose between the sound and feel of three classic power amp stages, shaping compression, natural drive, and dynamics. This, combined with three distinct preamp voicings and a 3-band semi-parametric EQ, enables the Unity U250 to deliver infinitely flexible bass tone and exceptional feel, regardless of your playing style.

The Unity U250 Bass Combo Amplifier is performance-optimized and powerful. Its deceptively simple controls allow you to quickly and easily create your tone, no matter the style. Choose from three unique voices and response controls to shape the sound in your head.

Push your creativity to new heights with built-in Chorus, Compression, and Octave effects. The Unity U250 is the perfect unit for both studio and stage, offering balanced XLR, USB connectivity, and more.

The Unity U250 offers Classic, Modern, and Flat voicings, making it perfect for playing any style. The Classic voicing offers a Valve-Inspired growl with a Vintage EQ, Modern offers High-headroom dynamics with advanced EQ, and Flat provides a totally flat signal that's clean and transparent.

Unity's unique response control adapts three power amp stages to shape compression and feel. The Linear response is powerful and articulate, the 6L6 packs the compression and punch of 6L6 power valves, and the 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.

Enhance your tone even further with Unity's built-in Chorus, Compressor, and Octaver effects. Perfect for any occasion, studio, or stage, the Unity U250 Bass Combo Amplifier is perfect for any musical environment with balanced XLR and USB connectivity and more. Experience the sound in your head with the Unity U250 250W 1x 15" Bass Combo Amplifier.
