How many hours have you spent scrolling through menus, tweaking knobs, or swapping pedals just to get close to the tone in your head? Positive Grid’s new BIAS X wants to end that ritual once and for all. Powered by the company’s Agentic AI, this software lets guitarists create tones by simply describing them in words, uploading a favorite track, or even throwing out wild prompts like “sunset over Saturn.”
Looking for a tight, saturated metal rhythm tone? Just type it in. Want the soaring lead sound from your favorite record? Upload the track, and BIAS X will recreate the tone automatically. If the sound isn’t quite there, simply say “more bite” or “less fuzz” and watch the AI fine-tune it in real time. It’s tone-shaping that feels more like a conversation than a chore.
Behind the scenes, BIAS X isn’t cutting corners. The engine was trained on over a million tones and built from deep research into 200 legendary amps. With 33 amp models, 63 effects, and premium cab sims, the software captures circuit-level dynamics like transformer sag and power amp response.
Whether you’re tracking at home or gigging live, BIAS X is built to fit right in. It runs as a standalone app or in any DAW, with ultra-low latency and minimal CPU drain. The cab section comes loaded with IRs from Adam “Nolly” Getgood, and stereo options let you craft huge, mix-ready sounds straight out of the box.
Here’s the kicker: BIAS X doesn’t just spit out presets — it learns from how you shape sound and evolves with your playing style. Your riffs, presets, and recordings stay private, but over time, the AI adapts to give you tones that feel even more personal. For players who want to spend less time fiddling and more time playing, BIAS X might just be the most exciting development since amp modeling itself.
