The Blackstar Unity Bass 250 stands out with its powerful 250-watt output, driven by a custom-designed Eminence 15-inch Opus speaker. This setup ensures clear, dynamic sound suited for both live performances and studio sessions. The amp features versatile effects, including built-in Chorus, Compressor, and Octaver, which expand your tonal options and enhance your sound.

Footswitchable Drives: The Unity Bass 250 includes three footswitchable drives—Overdrive, Distortion, and Fuzz. Each drive has user-controllable blend, allowing you to mix and match tones effortlessly. This feature enables you to switch between gritty overdrives and smooth fuzz tones with ease.

Tone Control: The amp provides a 3-band EQ with semi-parametric Mid control, offering precise tonal adjustments to match any playing style. Additionally, the unique Response control lets you choose from Linear, 6L6, and 6550 modes to tailor the amp’s response to your preference.

Connectivity and Practice Features: Connectivity options include USB audio out for direct recording, balanced XLR and ¼-inch Line Out, and D.I. / cabinet emulated line outputs for flexible recording and PA integration. The series effects loop and MP3 / Line in features allow for additional device connections. The headphone output, with independent level control, supports silent practice without disturbing others.

Additional Features: The amp also features a pad switch for active or passive instruments, input gain with clip indication, and a master volume control. For those needing more stage power, the Unity U2250ACT 1×15” Active cab can be linked to add 250 watts to your setup.
