## What is ToneStack?

ToneStack is the ultimate UNIVERSAL app for signal processing: with the LARGEST and BEST selection of AMPS & FX, the latest advancements in modeling technology, and an unbelievably powerful yet simple interface – it simply shreds all the other guys. 

Thanks to ToneStack's state-of-the-art “Virtual Circuit” technology, each ToneStack unit is the digital mirror image of a real analog topology. Unlike other FX apps that try to copycat with EQing and other gimmicks, ToneStack recreates the intricate designs of the real thing. The result is a warm, responsive tone with the natural behavior you find in analog units.

Best Selection of Pro Amps & FX

ToneStack offers a huge range of amps, cabs & FX: from sparkly clean to sizzling hot bias tube amps, iconic stompboxes, pro-grade rack units, and high-end reverbs, ToneStack is the most complete plugin suite on the iOS. 

Right away, enjoy 6 classic amps & cabs, and 21 meticulously designed FX. Expand to a total of 46 amps, 44 cabs, and 101 FX – the largest collection on iOS.

ToneStack also brings many powerful guitar FX to the iOS for the first time: polyphonic octaver, harmonizer, realistic spring reverbs, virtual-reel tape delays are just a few examples.

The Most Versatile Signal Chain on iOS

Why be limited with just 4 or 8 FX that other guys max you out at? ToneStack lets you run a whopping 64 amps & effects simultaneously* so you can let your imagination run wild.

For even more power, ToneStack includes our unique original ABY unit. Split your signal anywhere: run dual amp setups, switch or blend FX chains, or multiplex your signal via frequency splitting – countless permutations, all up to you.

You can match any amp with any cab (all cabs have 3 mics with distance & position settings); you can insert any unit anywhere – even between amps and cabs like a true FX loop. Managing your signal chain is as easy as dragging and dropping an icon!

inSTUDIO & Other Goodies

Wanna quickly jam out an idea, or cut a song and share it? ToneStack offers a powerful 8-Track recorder – first two tracks free — with plenty of user-friendly features. Fire up the built-in Tapedeck to quickly record an idea or create loops, or manipulate audio with its Hi-Q pitch & time shift. Import & export audio via email, WiFi, iTunes or copy/paste. Built-in tuner, metronome and a custom onSTAGE mode are just a few other amazing ToneStack features.

All the Pro Features of iOS

Enjoy the full power of the platform’s top MIDI and Preset systems. MIDI learn is super-intuitive thanks to ToneStack's WYSIWYG interface: all the amp & FX controls are MIDI-programmable. Effortlessly create UNLIMITED banks and presets – share them at the touch of a button. ToneStack is an Inter-App Audio effect, and works in any Audiobus slot. ToneStack also allows you to insert other Inter-App Audio apps anywhere in your signal chain.

### 5/5 — Love it! The Whammy pedal is perfect!

*2025-12-16*

Tones are great. That said,not all the tones are great, but most are very useable. I never use presets anyway. Create your own patches, and the sky is the limit. Have bought some of the amps and pedals,they do not disappoint...it’s a smorgasbord of sounds for not a lot of dough. I’m a seasoned musician ang studio guy,and I’m having a blast with this! Get it! PS. Recording is a breeze,and the studio is very straightforward,good for noobs ..

### 1/5 — Not the Pro app

*2025-05-23*

This app crashes a LOT and doesn’t work with IAA. The Tonestack Pro app that I found after getting frustrated with this is great. This was a waste of 10 dollars and really shouldn’t be on App Store any longer.

### 1/5 — 今のiPadでは使用出来ない。

*2025-03-27*

AUM>inter-App Audioで、第2世代 iPad Pro(iOS17)だと使用出来るが、第9世代 iPad(iOS17)だとノイズが発生、しかも　エフェクトーが掛からない。このアプリは、古いiPadしか対応しないようだ。Cubasis 2でも同じ現象。

### 1/5 — Avoid Yonac

*2025-02-08*

Yonac abandons apps after a short period. ToneStack and Magellan Jr are gone. All the money I spent on the apps and in app purchases? Gone.

The new ToneStack appears to be abandoned as of a few months ago. 

Unless you want to treat them like a charity for which you don't get an itemized deduction, avoid them.

### 5/5 — Love it

### 1/5 — これに落ち着いたね。

*2023-06-03*

他のアプリも試したが、しぶとく残っているのはこれだけ。エフェクターもアンプも買ってしまえば何台でも同じものを繋げるという変則的な事ができる。 ただIRIG HD2に似た他社ギターインターフェースには対応して無いので注意が必要。(文句はオーディオインターフェース作ったところに言えとポップアップが出てくる。)
5年前にバージョンアップしたのみだが
このアプリは数回のiOSのバージョンアップでも大した不具合は
なく動いた気がする。

### 3/5 — `i will put in a star or 5 later

*2023-05-20, version 3.3*

The app is not working after spending over $100 for in app purchases It better get back up soon. I do hope that you are not trying to manipulate me(us) into getting your new app(AuV3 dont matter to me) and I am not paying another 59.99 because I already paid a lot more.

### 1/5 — A REFUND IS IN ORDER

*2023-01-28, version 3.3*

App works fine by itself, however it DOES NOT WORK in my DAW as advertised, I would like my $9.99 back.

### 5/5 — It’s the best amp sim on any platform

*2022-11-26*

So many tones; it’s so worth it.

### 5/5 — Equalizer on the master bus

*2022-06-22*

Make an equalizer on the master bus! It is very lacking at concerts, when you need to urgently adjust the sound on all presets. Because of this, I had to go to another program. I hope you fix it!
