  • Amazing, BUT...

    By oSplicerr
    Let me just start off by saying I absolutely love this app, BUT, when I use my iRig 2 to use BIAS, I connect my aux to my amp that has an aux in, I plug it in and other apps like JamUp sound perfect in there but when I use BIAS it’s WAAY too quiet. Please look into this, I don’t use this app much anymore because of it, but i do really like this app!
  • Buzz sounds

    By Cool dude 366
    I'm sure this could work very well if it didnt have this distorted buzz sound even when my sound gate is at 100 and on a clean amp. Please fix this so I can enjoy this app
  • Terrible.

    By Asian dudde
    Get Tonebridge. This amp simulator makes so much extra noise even with noise gate at 100 percent. I have a strat loaded with humbuckers, and yet the amps make my guitar sound like a motorcycle when it doesn’t want to start. Save your five bucks and buy a really nice coffee.
  • The Best Thing Going

    By SpiritMonkee
    Without a doubt the best thing going for iPhone and iPad. No fizz, no buzz, no flop. Great bottom end too. Use it with AUM and add stereo FX. Use it with JamUp for a mono live set up. Could have been five stars but updates are poorly quality controlled. They tend to fix one thing and break another. Get that together PG...PLEASE!
  • Bias doesn’t cut it

    By timisme
    I had high hopes for this iPhone amp. I heard many good things about how it sounds like a real set of amps. I bought in to bias whole set of effects amps and stomp boxes. It’s weak and I can’t get anything to sound other than a harsh compressed sound. Back to the drawing board.
  • Doesn't work

    By Gregauletta
    I have both jamup pro and this app. Bias amp app has not worked in almost a year. No matter what you do I get the same flubby sound that cuts in and out. Using on a iPhone 6s. Is this app ever going to be fixed?
  • Good idea, horrible delivery

    By SalesTorch
    Product does not work like promised in videos. You cannot get he hissing and squeak out not matter how you adjust settings. Avoid this app
  • Sick tone

    By Mad beats
    Omg.. Playing for 20 years, would never have imagined I could dial in master of puppets tone on my phone... Sick! Be aware as I see at least one other wasn't. This is the tone engine, and will not have fx... but does have amazing tone. It does also integrate with another program, that you can run fx with. Great job!!
  • No Effects?

    By Ahmed Al-Najjar
    where's the effects?, worst app ever .. back my money
  • AMAZING!!!

    By Oxbig
    I'm kinda old school, and little behind the times and technology, but when I came across Bias Amp/FX in the App Store and they were doing a huge sale, like now, I decided to go for it.... Positive Grid has TOTALLY nailed it!!! Fast forward a couple of months and I decided to get the Pro Desktop version, another huge sale, I got it all... I'm speechless!!! I can't wait to see what they have for me next!!!
