Description
The Blackstar Unity 120 Bass Combo Amp is a powerhouse of versatility and innovation, crafted specifically for the discerning bass player. This amp offers a cornucopia of tonal options, allowing musicians to seamlessly transition from a valve-inspired growl to a high-headroom clean sound. With three distinctive preamp voicings—Classic, Modern, and Overdrive—you can tailor your sound to suit any genre or playing style.
The Unity 120 features a unique Response control, which lets you choose between the feel of three classic power amp stages: Linear, 6L6, and 6550. This empowers you to shape the amp's compression and feel, giving you the flexibility to craft your signature sound. For those who crave even more control, a 3-band EQ with a semi-parametric Mid knob is at your disposal, along with built-in effects like compression and chorus to enhance your tone further.
Connectivity is a major strength of the Unity 120, making it ideal for live performances, studio sessions, or home practice. The amp includes balanced XLR, USB connectivity, and an MP3/line input, ensuring you're ready for any scenario. Plus, the integrated link to the Unity U250ACT powered cabinet allows you to elevate your setup with an extra 250 watts of power if needed.
