BIAS HEAD

The Most Versatile Amp Head On The Planet

"BIAS Head allows you to design and match any amp tone on the fly."

"An insane amount of flexibility and tone customization."

SONIC FLEXIBILITY

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, the BIAS amp head is deeply rooted in the rich history of tube amplifier design while remaining aimed directly at the future.

INTUITIVE OPERATION

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.

POWERFUL SOFTWARE

If you want to dive headlong into the world of amp customization, BIAS Head comes with our amazing BIAS AMP software suite ($199 value), which allows you to recreate the sound and feel of nearly any existing guitar amplifier. Even better, it gives you the power to create an entirely new amp that is unique to you and the way YOU play.

Connect to the BIAS Head amp 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.

CONNECT YOUR AMP HEAD TO THE CLOUD

The BIAS Head guitar amplifier can connect to the Positive Grid ToneCloud®, a cloud-based community we’ve created specifically for guitarists and musicians. It’s much more than just an online storage tank for sounds - it’s a place to discover new ideas and new tones. You can download new amps created by artists and recording studios, backup and share your own creations with other guitarists in the community, and interact with other musicians with similar interests.

BIAS AMP software features the ability to Amp Match®, analyzing a source guitar tone and applying the necessary corrective processing to make a custom amp more closely match the original. Even if you don’t plan on matching amps yourself, you can still take advantage of the Tone Match feature by downloading custom amps other guitarists have matched from the ToneCloud®.

“The BIAS Head has a lot of flexibility, it’s able to dial in exactly what you are looking for. It’s very inspiring, and the amp match is incredible, I’m floored by it!” - MARC RIZZO
