Utilizing a similar component-based philosophy as our revolutionary BIAS Amp designer, Positive Grid’s BIAS Pedal enables you to virtually create your own custom pedal, with full control over the pedal’s circuit. Seamlessly integrated with BIAS FX, BIAS Pedal makes it possible to add your custom pedal to your BIAS FX pedalboard. Download thousands of customized pedals in our new BIAS Pedal ToneCloud®.

Design your dream pedal

For the first time ever you can easily design and modify your custom pedal down to the most detailed level – from the input volume, effect stages and gain control, pre and post EQ and much more. You can even change the pedal’s virtual guts as you would with a real analog pedal. For the utmost ease of use, BIAS Pedal comes with 17 distortion, 17 modulation and 24 delay presets, from blues to rock, alternative, metal, and everything in between.

BIAS FX Integration

You can easily open your custom pedal in BIAS FX’s dual signal effects chains for a whole new level of tone creativity. Now BIAS pedals can be integrated into the same signal chain as boosters, distortion, or fuzz pedals for live or studio use. And with its cross platform design, BIAS Pedal can be synced all across Mac, Windows, and iOS devices for instant access anywhere you work.

MN.Mike ,

Updates conflict.

For the Bias Pedal when trying to open after update it says I can’t open it,I must sign in with the Apple ID that was used to purchase this app. Now it started doing that with the Bias FX but it worked with the ID. I can’t restore Bias Pedal nor repurchase @ 9.99 ea. Plus I can’t use it as an inner app with all of my positive grid apps. Confused,Michael. I finally got it to work by deleting it then downloading it again. Scary, but it works.

Developer Response ,

Hi Michael, please write us on and we can provide more help there. Thank you!

I use BIAS FX 2 mobile, but i want to us this.

I can’t login to the Tone Cloud in Bias Pedal. But I’m logged in on biasfx. What’s the problem?

Lost Potential - Buggy on iPad Pro 11”

I really want to like this app. It has tremendous potential, but compared to the other Positive Grid apps it is quite buggy and crashes constantly.

The UI has not been updated for the latest iPads and I cannot log into Tone Cloud like I can for Bias FX2 or Bias Amp. Not sure if this is Abandonware, but it seems like it may be since the last update was 2 years ago. Pity.
