Positive Grid has introduced a major update to its BIAS series plugin, which now lets users describe their ideal guitar tone in plain language, or upload a song or guitar recording. In seconds, BIAS X‘s AI assistant will analyze and create a custom tone, identifying the amp, cabinet, and effect combination with stunning realism.
While Spark amps are great for jamming, practicing, and even performing, BIAS X is built for a different stage—your desktop. It’s an all-new software and DAW plugin made for creating and recording professional, mix-ready tones on Mac and Windows.
BIAS X features
- A brand-new Agentic AI engine that responds to your intent.
- Text-to-Tone and Music-to-Tone creation that generates custom tones in seconds.
- 33 all-new amps and 63 effects modeled with studio-grade DSP.
- Dual signal chains, parallel routing, and drag-and-drop workflow.
- Enhanced cab and mic simulation powered by Spectre Digital IRs.
- A complete overhaul of the UI, preset system, and creative flow.
Available in VST3, AU and AAX plugin formats, BIAS X is priced $149 USD. Owners of BIAS products (like BIAS FX 2 or BIAS Amp 2) or a Spark series guitar amp may qualify for upgrade pricing.
