Inside the tone.

BIAS X’s advanced sound engine analyzes preamps, power amps, and transformers with AI-enhanced precision. It captures circuit-level dynamics like transformer sag and power amp response—delivering 33 amp models with authentic compression, harmonic richness, and dynamic response that traditional modeling can’t match.

Each of our 63 effects utilizes Agentic DSP trained on vintage analog gear to recreate the subtle non-linear behaviors and dynamic sensitivity that give classic pedals their distinctive character.

BIAS X uses high-resolution impulse responses and impedance-matched processing to preserve the natural interaction between amp and speaker. A visual mic-placement interface makes it easy to dial in tones quickly.

An intuitive drag-and-drop interface and overhauled preset system make tone building and organization fast and effortless. Dual-patch signal chain architecture allows you to build complex routing configurations, without the noise and impedance limitations of physical setups.
