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.

BIAS FX is fully integrated with BIAS AMP so you can easily import BIAS your favorite vintage, boutique or high gain amps to have em available into your pedalboard for studio or live performance.

Key features:

- 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.

Outstanding Customer support


I experienced a real difficult issue with an in app purchase for Bias FX. Went around in circles with support and Apple Support but have to say that after a few days Positive Grid was able to get me a working solution. I know others mention poor support but I wanted to share while my issues were indeed frustrating the app developer did care and did get me a fix.

The App itself is fantastic. I also own Jam Up and Amplitude and each has its good and bad. I am more familiar with the Positive Grid stuff and like that we can share our creations.

Now that my technical issues have been fixed, TIME TO JAM !!!

Hi there, thanks so much for the feedback! I'm really glad to know we did manage to sort out the problem together. It's absolutely great to be able to help out and see you enjoy our apps again! All the best!

I'm convinced.


I'm a former professional, current hobbyist. Old school. And this app has completely convinced me. The tones are really solid (clean tones not quite as convincing as distorted, but I'm also getting better at dialing in good sounds. More user error than program error I think.). I find this app more intuitive than others I've tried. I'm still exploring how to use this live. That requires some external devices (iBoard etc). If that works then I'll move this up to 5 stars.

WOW!! sounds amazing!!


this app truly sounds amazing!! so easy to tweak and create great tones!! been using it in the studio and it it’s hard to believe it’s not a real guitar cab with a mic. would have given 5 stars but there are some glitchy things. not sure if it’s IOs 11 or not but when i go to midi control assignments the edit and done buttons are on top of each other and i can’t back out of the page. have to the close the app and relaunch.
