BIAS HEAD PROCESSOR (Manufacturer refurbished)

(Non Powered) This needs a separate power amp.

These units are brand new (never sold) but have been upgraded to the latest revision. 

We are selling the last of our BIAS HEAD head stock at a special clearance price as there is a new model coming in May 2020). 


The world’s first cross-platform guitar amplifier, BIAS Head integrates seamlessly with BIAS Amp for mobile and desktop use: you can design your custom amp and create Amp Match models in real time.



BIAS Head Processor is a non-powered guitar and bass amplifier that accurately captures any amp tone in the world, including the cab and even mic position. You can safely pair it with your power amp and cabinet of choice. With the included BIAS Amp Pro software, you can share and download thousands of amp match models and save them right in the head.


If you want to dive headlong into the world of amp customization, BIAS Head comes with the amazing BIAS AMP 2 software suite ($199 value), which allows you to recreate the sound and feel of nearly any existing 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 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.  BIAS AMP 2 software works on MAC / PC / iPad and iPhone.



Amp Match® lets you capture or download any tube amp tone and sync it with your desktop and mobile devices. You can then use the exact same tone with BIAS Head on stage, in the studio or while practicing at home.


Swap out the virtual tube types, preamp, tone stacks, transformer, cab and mic position to create your own signature sound, component by component.
