Unity Pro Bass are the result of countless hours of technical research and benchmarking against the most iconic historic references.
Designed from the ground up by bass players, for bass players they are straight forward and powerful.
The new Unity Pro Bass System’s deceptively simple controls allow you to quickly and easily create your tone, with rock solid bass, detailed dynamics and innovative features in a compact package from 30 Watts to 500 Watts.
Blackstar’s unique Response control allows the player to choose between the sound and feel of three classic power amp stages, shaping compression, natural drive and dynamics. Combined with three distinct preamp voicings and a 3-band semi-parametric EQ, Unity produces infinitely flexible bass tone and exceptional feel, whatever your playing style.
