It gives you an easy to use drag-and-drop interface that includes everything that a guitar player needs for massive tone, with a collection of insanely great-sounding guitar pedalboards, dual amps setup, ultra-high definition stereo rack effects, and dual signal chain.

- Pedalboard View shows all the effects and amps in the currently loaded preset at once
- Global Settings optimizes BIAS FX’s output to sound the best in any environment—including sending to a mixer, amp head or combo or stack power amp—by letting you EQ and selectively deactivate the app’s preamp, tone stack, power amp and cab separately for each destination.

Developer Response

Hi, thanks for the feedback! There will be a BIAS FX update with this issue fixed. You will be seeing the update in 2 days or even sooner! Please try it out and let us know if it's up and working then! Cheers!

Excellent mais...


Il serait bien que le BPM soit sauvegardé dans l'enregistrement des presets.

Et de pouvoir copy/past les réglages.

Bien mieux que les autres


Que ceux qui hésitent à passer aux effets numériques franchissent le pas. Cette application saura vous satisfaire.

Bias FX offrent un large choix de pédales et d’amplis avec un son bien plus fidèle que ses concurrents. Couplé à Bias Amp 2, c’est un must.

Les bassistes ne sont pas oubliés.
Il manque peut-être encore quelques effets, mais comme les développeurs sont à l’écoute, ils risquent de vite apparaître.
