BIAS AMP 2 Mobile seamlessly integrates with Positive Grid’s ToneCloud®, which is far more than a simple storage tank for your own custom tones - it’s an active community where thousands of guitarists upload, share and discuss tones.

To take your tones to the next level, there are 9 full-featured reverbs in BIAS AMP 2 Mobile. These aren’t just simple two-knob reverbs either - they range from lush halls and chambers to intimate rooms, and each reverb has control of decay time, mix level, high and low cut filters, damping and dwell.
BIAS AMP 2 Mobile integrates seamlessly with Positive Grid's BIAS FX and JamUp guitar multi-effects apps for iPad, expanding BIAS AMP 2 Mobile into a powerful and completely unified professional guitar system for live use, recording and jamming. Both JamUp and JamUp Pro include effects processors, Jam player, 8-track recorder and phrase sampler, tuner and metronome, effectively turning BIAS AMP 2 Mobile into a recording studio and top-of-the-line practice utility.

Amp sim sound good, but UI not scaled for 12.9” iPad Pro
This is my favorite amp sim especially when combined with Bias FX. That said, I am disappointed with the UI on the 12.9” iPad Pro (1st gen). It is scaled for a regular iPad and the screen is tiny. This is one of things holding me back from paying for the full version. It would also be nice to have a simple IR loader for the iPad version integrated into the app. Hoping the next update fixes the screen issue.
Update: With the screen issue fixed Bias Amp 2 is probably the best amp sim app out right now. Despite having to pay extra to unlock all the features, the app is a more versatile tool than ever before and conforms with standard mic placement practices (ex. 121 and 57 combo). I use this program with an older Apogee JAM and have not had any issues with sound or crackling. What I would like to see in the future is more 3rd party IR integration into the app. Overall, Bias Amp 2 a very useful tool for guitarists and a hell of a lot of fun to rock on.
Developer Response ,
Hi rcguitarguy, We are really sorry for the problem you are encountering. Right now we are focusing on the fix of the screensize and we hope to release a fixed update very soon!
One Huge App!
I Love the Control I get with Bias Amp 2, but there is something Major you should consider...When I go from Bias FX to Bias Amp 2 I just have the stripped down amp to work on with no effects except a Mono Reverb. Then when I link back over to Bias FX again, the amp sounds Totally Different than when I just worked on it in the Bias Amp 2 App due to what effects I use with it. It would be Much Better if you made it all One Big App so I can work on sounds as they will sound when finished in Bias FX. The Cabinets are over in Bias Amp 2 and can alter the sound Drastically. All the Amp adjustments would be much easier to work on if they were a part of the Amp adjustments in Bias FX instead of switching back and forth and having to Guess what it will sound like in BiasFX. Bias Pedal is easier to go back and forth, so that isn’t a big deal. If I could adjust all the Amp Settings over in Bias FX with the Effects I want to add, I could get a better result than guessing what it will sound like. You could just have in-app purchases instead of getting both apps.
Bias fx has no output after the update
After updating to bias amp 2 I get no sound out of bias fx. I see the input meter is receiving sound but no output. When opening the amp in bias amp 2 I get a signal path error 0. No reverb block in signal path. Only when you turn off the cab in global settings you get some sound but wth out the cab sound. I go directly to PA so that almost ruined a gig . Luckily I imported an amp from bias amp 2 that was working in bias fx so I could at least finish the gig. The acoustic imaging amp works also. Please fix this since I don’t want to lose my presets.
Works perfectly now thank you for fixing the issue. I had to write the bad review because it ruined a gig for me. I’ve been using bias fx Ipad to gig professionally now for over 2 years and it’s been rock solid until then. Works great now best of its kind. Six stars
