What's New in Ampz

1.6.1

August 23, 2026

Two fixes for impulse responses. FIXED: In dual IR mode, where the left and right channels each load their own cabinet, the right-hand cab was lost when switching presets. Both cabs are now saved and restored. FIXED: In the AUv3 plugin, loading one of your Ampz presets and then saving the project in your host left the cabinets out of the saved project. They now save and reload with the rest of the rig.

Great App, but

it would be nice if the app itself could host AUv3 units too. 100 Presets is great, looper and drum machine are perfect additions for standalone use. Wow and manual!!

Response from developer

Thanks! Glad the presets, looper, and drum machine are working well for your standalone rig, and that the manual landed too. Turning Ampz into a host that loads other AUv3 units is something we're thinking about, though I can't promise it yet. For now it works the other way around: Ampz is itself an AUv3 effect you can load into a host like AUM or Loopy Pro alongside your other units. Thanks for the great suggestion and the kind words. - Jonathan

Superb

What a brilliantly conceived and designed application. A real pleasure to use, and I’m bowled over by the realism of neural amp modelling (which is new to me).

The functionality, MIDI in particular, seems to offer everything needed for live performance. Just two caveats on this from my side. First, is it stable enough? I hope so but I’ve not yet used it anything like enough to know the answer to this. Second, I’m running it on an iPad mini, which seems like a good platform for live work. But the Ampz Live view doesn’t yet use all the available screen space to best effect, with things that could be big and bold appearing too small for my own preference. But this alone wouldn’t stop it from being workable.

The app is new so I’m sure that the dev team will work this through. They’ve done a fantastic job!

Response from developer

We're really glad the amp modeling and the MIDI feature set are clicking for live use, since that's exactly what we built it for.On your two points: stability is our top priority, and every release goes through on-device testing before it ships. If you ever hit anything unexpected, please reach out so we can look into it directly. On the iPad mini layout, a recent update (1.5.0) specifically reworked the iPad Live view to use the full screen: the controls scale up, the knob grid spreads out and grows larger, and text and the toolbar are sized up for tablet. Make sure you're on the latest version and let us know how it feels on the mini. Thanks again for taking the time to review and for downloading. - Jonathan

Amazing!

Wow! I just bought the tonex one plus pedal and this….Ampz is 10xs better….I messed around three and a half hours with Tonex with software and still couldn’t get it to work. I said I’m done! I saw this advertised and bought it the same day. The effects are really decent and the integration of tone3000 is sooooooo simple!

Response from developer

Thank you, this means a lot! I'm glad Ampz got you playing instead of troubleshooting. Also happy the Tone3000 integration and the effects are working for you. There's an iPad-optimized update out now, and more on the way. If you ever hit a snag or have a request, reach out. I read everything. (And nice username JMP 2203. 🤘) Jonathan

AUv3 hits the spot

What a great plugin. It sounds great as a AUV3 in Loopy Pro while saving about 15% of CPU power on my iPad compared to my other NAM plugin. The built in effects and IR loader will prove very useful. Thank you !

Response from developer

Thanks so much for taking the app to band practice! I'm thrilled to hear the sound and Live Mode are hitting the mark for you. I have some great news regarding Loopy Pro: we just released v1 of our AUv3 support! Make sure you update to the latest version, and you'll be able to load it right up. We are actively refining the AUv3 experience, so stay tuned for even more improvements there. I also really appreciate you flagging the audio pop when engaging the delay on your M1 iPad. I'm looking into this bug right now so we can get it smoothed out in an upcoming patch. Have a great time gigging this summer, and feel free to reach out to jonathan@ampz.app anytime!

Excellent app

The exact NAM loader I was looking for! Supports a2, integration with website to download tones straight from app and quality of life features like bread and butter fx mean I can do everything in the app for quick jams

Response from developer

Thanks so much for the fantastic review! It is incredibly rewarding to hear it's hitting the mark for you. Making it seamless to grab tones and immediately dial them in with included FX was a huge priority. Keep an eye out for more updates, and happy jamming!
