BIAS Head is a guitar amplifier like no other. Inside this 600-watt beast lies the most precise and outrageous-sounding models of vintage, modern and boutique guitar amps you’ll ever hear. We’re talking killer tone that responds to your playing like the original amps. Positive Grid modeled the best-sounding guitar amps down to their individual electronic components, including the transformers, tubes, resistors and capacitors. The result is a stunning response to your feel—whether you’re picking hard or soft, tapping, doing volume swells, or using a slide or wah pedal—that sounds just like you’re playing through the original amps. BIAS Head’s Amp Match function also lets you easily capture the exact sound of any guitar amp, including rare amps owned by your buddies and amps recorded on rock’s most iconic records.

Create your Own Signature Sound

Load any amp model, and then instantly modify its design with the simple turn of a knob or by flipping a switch on BIAS Head’s friendly front-panel. It couldn’t be easier. Twist a knob to immediately switch from an ultra-clean solid-state head to a velvety tube amp—or create hybrid versions of classic amps. Completely change the tubes’ circuit design by turning just one knob to make the amp distort smoothly or break up immediately. Twist another knob to add up to four additional tube stages for extra gain on soaring solos. Adjust the balance of power amp and preamp distortion by turning two knobs. Flip a switch to add a cabinet sim. Awesome tones ranging from glassy to overdriven—and everything in between—are yours in a heartbeat. And BIAS Head’s tone stacks for Bass, Middle, Treble and Presence change their tone with each amp model you play through, sounding like the tone stacks on the original amps.

BIAS Head’s rear panel has all the connections you’ll ever need for connecting an external cab for use onstage, plugging directly into recording gear, looping out to your favorite effects boxes, and rehearsing with your band. All of the modifications you make to its stock amps are stored in BIAS Head, ready to use anywhere no matter what kind of gig you’re playing. And with its 600W of floor-rattling power, BIAS Head will fill any room from small club to large stadium.
