Product details

BIAS Amp represents an entirely new concept in guitar sound and instead of providing a fixed number of amp models, the tone-creation possibilities are virtually infinite. BIAS Amp features Tone Cloud, an amp sharing platform a where users can easily download artist’s signature amps, or try out the latest and most popular matched amp models created by their fellow guitarists from around the world.

  • Amp Design: With BIAS amp you can create custom amp models in a new way that was ever thought possible. For the first time in history, guitar players can easily design, modify and capture the most unique, expressive and soulful tones, store them in the digital domain and recall them at any time for any recording application. Thanks to all the customization features on BIAS Amp, anyone can easily create or modify any amp models by swapping out the tubes, preamp, transformer, tone stacks, cab and mic to create their own custom amps and unique signature sound.

  • Amp Match: Accurately capture the sound of all your favorite tube amps with BIAS Amp. Positive Grid’s Amp Match Technology utilizes a collection of underlying technologies to analyze and compare your currently selected BIAS amp model and the sound of any classic or high gain target tube amp, its speaker cabinet, and the microphones used to capture its real sound. It then implements the tonal compensation and enhancements necessary to make your custom amp model sound like a real target tube amp.

  • Impulse Response Loader: With the new IR Loader in BIAS Professional, you are able to capture the characteristics -both in frequency and time- of an entire signal chain, including the sampled speaker, the microphone, and the room it’s in, allowing any session musician to maintain consistency between sessions. With Impulse Responses (IRs) Loader in BIAS Amp Professional, you are able to load any cab or mic impulse responses (IRs) to further customize your BIAS Amp tone and export them into BIAS FX.

  • ToneCloud: Share and download artist- and user-designed and matched amps right inside Positive Grid’s ToneCloud. The ToneCloud is the best way to sync your favorite amp presets over devices, take your amp collection on the road with you with iOS, or share your custom amps and tones with a growing community all over the world! There are hundreds of classic and modern amps available on ToneCloud, and the banquet keeps getting bigger and bigger. We are always working with professional artists and session players from all over the world to create a massive, ever-growing community.
