BIAS Rack is a rackmount amplifier that was made for the stage - it sounds and feels like your favorite classic and boutique tube amps, but offers entirely new sonic flexibility. The advanced component emulation engine captures the warmth, girth and feel of real tube amps, authentically recreating the complex circuit behaviors that make them do what they do. From djent to jazz and everything in between, our BIAS Rack is deeply rooted in the rich history of tube amplifier design while remaining aimed directly at the future.

BIAS AMP Pro Software

Connect via built-in Bluetooth or USB, and open up a world of component options previously only available with a soldering iron: choose between different preamp and power amp circuits, change the tubes and transformers, add clipping diodes and try out different rectifiers - all completely authentic and all in real time. It’s like having a boutique amplifier workshop at your fingertips.
