BIAS Head sounds and feels like your favorite classic and boutique tube amplifiers, but offers entirely new 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, BIAS Head is deeply rooted in the rich history of tube amplifier design while remaining aimed directly at the future.
Harnessing the power of BIAS Head is easy - just select one of the 25 onboard presets, grab a knob and start tweaking. Need more grit on your clean tone? Add another tube stage to the preamp. Want the power amp to feel more aggressive? Change the circuit topology and push the virtual power tubes harder. Prefer a crisper treble response? Flip the power amp presence switch to Modern and hear the top end open up. All of this tweaking is possible directly from the front panel knobs, so it’s completely intuitive - no laptop or mobile device required.
