Blackstar Unity 250
Blackstar · amplifier
The Blackstar Unity 250 is a 250-watt solid-state bass combo amplifier providing stage-capable output for medium venue gigging. Three preamp voicings — flat, modern, and classic — cover clean through Bassman and SVT-adjacent tonal characters. Semi-parametric sweepable mid and three-band EQ give detailed frequency control. A drive control blends overdrive, distortion, or fuzz into the clean signal for grit without a separate pedal. A response control simulates valve-stage character in the solid-state power section. At 250 watts the Unity 250 delivers significant stage volume with headroom for dynamic bass playing and handles medium club environments without PA support.
