Say goodbye to hours of painful tone tweaking: Positive Grid’s new BIAS X platform uses AI to deliver the perfect guitar tone instantly
Sick of endless knob-fiddling to get that perfect tone? Positive Grid’s latest AI-powered guitar tone platform BIAS X is here to change that. Available for Mac and PC, BIAS X combines cutting-edge AI with a next-generation tone engine, taking musicians from a spark of an idea to a mix-ready sound in just moments.
From subtle dynamics and soaring leads to punchy modern metal and dreamy ambient swells, BIAS X delivers tones with an authenticity that mirrors real tubes, speakers, and circuits. Whether used as a standalone tone lab or as a DAW plugin, BIAS X is designed to help players spend more time making music and less time fiddling with settings.

What really sets BIAS X apart is its use of agentic AI, which is said to “understand tone like a musician”. Players can describe the sound they want – via text prompts referencing a favourite artist, song, genre, or even an abstract feeling – and the software generates a matching tone almost instantly. Musicians can also upload audio clips to recreate tones or request iterative refinements such as “more bite,” “less fuzz,” or “add crunch”. This dramatically streamlines the creative workflow, which is clearly one of BIAS X’s primary goals.
The platform itself comes equipped with 33 amps, 62 effects, and an all-new cab simulation. All of which have been crafted with an advanced tone engine that combines decades of Positive Grid’s amp and effects modelling expertise with machine learning and circuit-level simulation.
Over 200 classic amps were analysed during development to capture their tonal character, while adaptive circuit modelling and harmonic fingerprinting ensure that every note responds dynamically to a guitarist’s pick, volume, and playing style.
BIAS X also features an intuitive, drag-and-drop interface – reminiscent of Positive Grid’s popular BIAS FX 2 amp and effects suite – that encourages fast experimentation without breaking creative flow. Musicians can easily mix and match amps, cabinets, and effects to build custom rigs, while the revamped preset manager and gear browser make it simple to recall, compare, or swap gear on the fly.
As with all AI learning models, BIAS X evolves with the user, which means it will, in theory, adapt to your preferred style and preferences the more you play.
BIAS X is available for $149. Check out the software in action below.
