Amp ONE - Guitar amps and effects processor based on connection of the circuit simulation and machine learning

This app is so far, the best guitar app I have on my iPad. Bravo!

I’ve tried most of the popular amp modeling software, and to my ears this is the most accurate reproduction of a good tube amp I’ve heard, tied with peavey revalver. Everything included sounds fantastic. Responds like a tube amp, thrilled with this one.

And it’s a pretty small footprint, too. I can’t access all the options in the preferences, though. I can’t see all of them.

I feel like I have become an expert on Amp Sims lately. Unlike other apps with a little catch ($$) along the way, there’s absolutely nothing to buy or subscribe to, no ads, just an extremely well designed and thoughtful app with all the features you could want. It sounds great. If you are looking into learning how to use your iPad as an amazing amp with the standard pedals this is the place to start before you spend any money on anything else. Thank you very much to the developers for making such a wonderful app available to everyone!

This is hands down the best! People don’t review it, maybe because it’s free (which is insane, I got it when it was 10 bucks and I would spend twice as much for it any time) and because of that they don’t give credit for it, after all how good can a freebie be, right? I own pretty much all of the amp emulations on iOS but nothing comes even close to the realisim and sound quality of this app! Almost indistinguishable from the real thing including response and everything! Creamy smooth and crunchy in the same time, best distortion I ever heard in digital form. Their electronic components simulation technology is the best in the industry imo, they should be more recognized. These guys are the best, period, check out their desktop plugins too, very reasonably priced and amazing quality! Support them! Thank you for making this app free!

Like most guitar players I have ALL the guitar amp sims with all the content unlocked. There are other apps with much prettier interfaces but none of them sound as rich as this one. The only negative is that the app hasn't been updated to AUV3 but that hasn’t stopped me from using it. I find myself getting carried away for hours in total tonal bliss. The feel is absolutely amazing! If you care more about sound and feel than you do about a fancy/pretty interface then you owe it to yourself to buy this app.

Hands down the best sounding fx/amp modeling I’ve tried. Be sure to turn on setting ‘output for mix’ if you are output your audio to anything other than a guitar amp/cab. The audio quality will suffer greatly otherwise. Positive grid, IK multimedia, line6; you guys should take notice and maybe buy the developer’s IP or offer them jobs. Icing on this cake is it’s free. thank you devs! -DL

Please update AmpOne to be used as a proper AU plugin. I very much want so badly to be able to use this app in GarageBand, but inter app audio has too many limitations. None of the other guitar amp sims for iPad sound or feel as real as AmpOne. Please update. I would gladly pay to be able to use AmpOne in my recordings. 5 stars, money, and endless praise await the developers…

Would love to see more amp and pedal sims added to the mix. Gotta be careful about blowing your ears out with this one, so check your levels before using.

I’m not a gear-head. Don’t even own a real amp anymore. I just want something to plug into once in a while and goof around with as quickly as possible. Amp ONE makes my noodling around sound better than I have any right to, with absolutely zero effort. I love it.
