### 1/5 — Help  - No product support

*2026-06-09*

The app was working fine last year when I bought it but after period of not using it and iOS updates all the tones seem to have lost their quality and everything sounds off. I don’t use Facebook or any of the other social media platforms Yonac use so there’s no way to get support from the manufacturers. 

I appreciate I might be an old man but I’d hope that would be better way of getting some support without having to write a complaint review.

### 4/5 — Great App (could use an update)

*2026-04-11*

If it fit the larger iPhone screens better it would be close to perfect.

### 2/5 — Only option to expand is to buy a huge bundle

*2026-02-04*

Right now you can’t add any individual effects without buying a $60 bundle. Complete disregard for customization without paying a fortune!

### 1/5 — Don’t touch it.

*2026-01-20*

I don’t usually review but I won’t ignore the way these guys handle their app. I got this to look into playing BASS with it, meaning because they only have 1 other purchase to buy everything else I would have to buy their “pot o gold” to use the bass sounds. I’m only interested in bass and it already starts with a $10 purchase. I’m not about to spend over $60 just for these bass sounds. They denied my refund both times for the parts I cannot use. Scummy.

### 1/5 — No tech support. No communication. Ur on ur own.

*2026-01-16*

The only way to communicate with Yonac is thru Facebook. I’ve tried to contact them several times now and they do not respond to inquiries. The app is Okay. Cost $59 bucks to get the full benefit. Just realize, if you have any trouble, you’re on your own. Don’t expect them to respond.

### 4/5 — A few bugs

*2026-01-13*

I love the app. It has some great tones and sounds but it seems a little bit buggy. My problem with this app is that it seems like midi assignments won’t when I assign a midi cc the app seems to not remember it, and I have to reprogram it every time.

### 3/5 — Expensive given extremely limited support

*2025-11-26, version 1.6*

The app is fine, but $70 for an upgrade? Not until I have some support. Support for this app is only available through social media like Facebook and twitter. I do not use social media; i find my life is much more pleasant playing music instead of doom scrolling.

I’ve had a question now for over 2 weeks yet I cannot get any response from the developer(s). I now have a few questions and it seems I must resign myself to never hearing from the developers. It seems they have no interest in actively supporting their app.

Again, decent app, works more or less as advertised, but the $10 entry is extremely limited in access to pedals. Absolutely NONE of the included presets will work BECAUSE THEY ARE ALL BUILT FROM THE $70 UPGRADED VERSION! So, yeah, the “free stuff” isn’t free: it will cost you an ADDITIONAL $70 to be able to use ANY of the presets included with the app.

Also, the manual is thinner than the morality of a MAGA disciple. If you aren’t a programmer (or have programming experience) and don’t have a lot of time and patience, this app will seriously piss you off. It will get the job done, but with much frustration and without any guidance or assistance whatsoever.

So far its working, but I am seeking a more effective, affordable and supported application to base my work on. This one ain’t it.

### 1/5 — A bit disappointed

*2025-10-16*

As a bass player I was a little disappointed at the limited amps and fx available for bass vs the guitar. Especially when you are already paying £10 upfront. Now if I want more bass amps and fx I need to pay another £60!!! Gutted! It’s a shame as the sounds on YouTube sounded great.

### 4/5 — Honestly - better than $100+ name brands

*2025-10-05*

ToneStack Pro is a strong contender in the amp & effects simulator landscape. It delivers excellent value, very good sound quality, and an easier preset/rig-building workflow than many rivals. If you’re switching between Amplitude, Bias FX, or similar apps, ToneStack Pro won’t make you feel like you stepped backward.

1.	Sound Quality
ToneStack Pro’s DSP and modeling are well-polished — clean tones, punchy overdrive/distortion, lush reverbs and delays. In many cases, the sound is equal to, and sometimes better than, what I’ve heard in Amplitude and Bias. Especially for mid-gain and ambient textures, ToneStack Pro often wins out in richness and stereo presence.
	2.	Preset / Rig Building Ease
Building your tone (amp + cab + effects chain) is intuitive. Drag-and-drop for signal flow, easy mixing/matching of cabs & amps, a pretty straightforward preset manager, and good options for editing. Compared to apps like Bias, where sometimes dialing in settings feels fiddly or buried in menus, ToneStack Pro makes this process more accessible.
	3.	Feature Set
	•	Large library of amps, cabs, and effects (70 amps, 68 cabs, 140+ effects in the full collection).  
	•	AUv3 support and running multiple instances is great. Try running 3 instances of Amplitude or others in one session on a brand new computer, and watch your cpu die.
	4.	Workflow & Usability
Preset management is solid: saving, organizing, sharing presets is easy. The interface is clean, responsive. Dragging effects into the chain, switching amps, adjusting effects all feel well designed. This smoothness helps reduce the “tweak fatigue” that sometimes comes with other amp sims.
Honestly, I own all of the apps named, Genome, Tonex, almost all of them. This app is much better.

### 5/5 — Excellent sound; Outstanding app

*2025-07-28*

TL;DR:My highest recommendation for an application. Buy this application and rest assured that you’re going to get outstanding sounds, great ease of use and very smooth functionality.
I’ve been using this application for over two years and should’ve written a review before now. This application is one that I use on an almost daily basis I have all of the main brand-name iOS apps, NAM, TONEX, TH-U; but I come back to this application for the sheer usefulness of it. Being able to set up and prototype of line with multiple apps, multiple cabs to fine-tune or determine what sound works best is invaluable usefulness to me. Additionally when you insert a element amp cab affect you can rest assured it is almost always set up correctly for insertion into the line without just being over the top or having to waste a lot of time trying to figure out the best way to use the effect. This app just works. It works the way you expect it and it fits into my workflow effortlessly. I encourage you to buy this application as I believe that you will find a lot of usefulness for not a lot of money. You don’t need the pot of gold extension, but it does offer a lot of amps, that you will find useful and more effects. Highest recommendation.

## Version history (last 5 releases)

### 1.6 — 2025-05-12

• Adds a new MIDI Learn option for binary FX parameters. Binary parameters can now be assigned a threshold MIDI value. This is particularly useful in manipulating such parameters using continuous controls (for example, using an expression pedal to turn a unit on or off at a specific position of its travel).
• Other optimizations and improvements.

### 1.5 — 2024-11-23

• Fixes an issue where BPM display wasn't updated in the standalone app when MIDI clock sync is enabled
• Fixes an issue where MIDI Effect AUv3 could load deprecated fullstate values

### 1.4 — 2024-11-08

This is an important update that modernizes the MIDI functionality in the AUv3 context, and also ensures general robustness for the iOS 18. In addition, audio algorithms used in pitch modulation effects receive significant upgrades that result in superior audio quality.

ToneStack PRO now provides an additional AUv3 plugin titled “ToneStack PRO MIDI,” which is a MIDI-controllable deployment optimized for current AUv3 conventions. Users who wish to control the ToneStack PRO plugin via MIDI should instantiate this version instead of the one titled “ToneStack PRO.” If your plugin hosts / DAWs don’t automatically route MIDI into FX plugins, please refer to their documentation to learn how to do so.

The old AUv3 plugin is still included as simply “ToneStack PRO,” but no longer supports MIDI control as the frameworks used are now deprecated. If you wish to switch to the MIDI-enabled version of the plugin in your existing projects, simply replace “ToneStack PRO” with “ToneStack PRO MIDI” in the plugins list of your DAW track.

The above update does not affect the MIDI functionality of the standalone app in any way.

### 1.3 — 2024-03-06

Fixes an issue in the AUv3 context where tempo-syncable effects such as delays may fail to respond to host tempo changes.

### 1.2 — 2024-02-07

• Increases robustness of the MIDI implementation
• Other improvements & fixes
