BIAS Desktop is an audio plug-in (AAX/AU/VST) for Mac OS X and Windows, and it’s all about guitar tone.
Instead of providing a fixed number of amp models, BIAS Desktop represents an entire new concept: you can virtually design your own amps, match any tube amplifiers, and share or download thousands of amp models from ToneCloud. It’s designed for studio recording and you can sync with BIAS Mobile and take it to a gig.
BIAS Desktop has the most advanced tube sound engine, its simple interface makes it possible to go deeper to pursue the tones you have envisioned, and Amp Matching Technology allows you to capture your golden tube amplifier, and finally you can share and download amp models from ToneCloud, just like Spotify for amps.
