Blackstar Unity Bass 700 Head
Blackstar · amplifier
The Blackstar Unity Bass 700 Head is a 700-watt solid-state bass amplifier head, the highest-output model in the Unity Bass series, designed for professional stage use with external speaker cabinets. The Unity platform's three preamp voicings — flat, modern, and classic — deliver tonal character from clean through Bassman and SVT-adjacent sounds. Semi-parametric mid and three-band EQ provide detailed frequency management. A drive control blends overdrive, distortion, or fuzz into the clean signal. A response control simulates valve-stage dynamics in the solid-state power section. At 700 watts the head drives large and demanding cabinet configurations for the biggest stage applications in the Unity range.
