Positive Grid Bias FX 2

Positive Grid Bias FX 2 turns a computer into a fully customizable guitar and bass rig, offering a virtual collection of amps, cabinets, pedals, and effects. The software includes a re‑engineered DSP engine that simulates point‑to‑point circuitry and vacuum‑tube dynamics, delivering hyper‑realistic tone modeling for both electric and acoustic instruments. Users can start from thousands of preset tones or build their own from scratch, adjusting parameters to achieve any desired sound.

The interface is designed for efficient workflow on macOS (and Windows), with smart controls that keep the UI unobtrusive while providing deep access to amp and effect parameters. A large tone library—over 50,000 presets—serves as a source of inspiration, and the system supports both standalone operation and plugin use within digital audio workstations.

Targeted at guitarists and bassists of all skill levels, Bias FX 2 is intended for practice, recording, and live performance, offering a comprehensive, searchable tone‑creation environment without the need for physical hardware.
