BIAS Head and BIAS Rack series are the first cross-platform amplifier/processor units that allow you to design your dream amp tone, component by component, right from the amp's front panel. Expand further customization using the Amp Match feature and ToneCloud, included in BIAS Amp Professional for Mac/PC.
Overview
For the first time in history, guitar players can easily design, modify, and capture the most unique, expressive, and soulful tones, and use them for any recording and live performance application.
BIAS Head and BIAS Rack represent an entirely new concept in guitar sound. Their engine features the most authentic tube modeling, seamlessly integrated with desktop and mobile apps, making it possible for guitar players to edit more deeply to create the tones they could only have imagined.
Additionally, our Amp Match Technology allows users to capture their favorite tube amplifier (or someone else's!), then share that amp and download other amp models on ToneCloud.
Both BIAS Head and BIAS Rack are perfectly suited for guitar and bass players and have been tested extensively to ensure the best experience in all settings—live, studio, and home use.
What's the Difference?
BIAS Head: A traditional amplifier head form factor with 600W of power, designed for guitar cabinets or direct output applications.
BIAS Rack: A rackmount-style amplifier with the same insane tone and characteristics as BIAS Head, designed to fit standard 19" rack cases.
Both models are available in two versions:
- Amplifier version (Silver): Features a built-in 600W power amp for connecting to cabinets
- Processor version (Black): No power amp, designed for direct output or integration with external power amps
Software Updates
The Digital Age is wonderful in so many ways—one of which is the power of the internet. Because BIAS Head and BIAS Rack are driven by firmware inside the unit and by BIAS Amp Professional desktop software, we update regularly to advance the use of these amplifiers in many ways.
Each time you connect your Head or Rack, there will be a notification at the top of the software when an update is available—for both the hardware firmware and the iOS/desktop versions.
