### 1/5 — Pas de sauvegarde des presets

*2025-09-16, version 1.3.26*

L'application détecte facilement le tank g. Le problème est que l'application confirme la sauvegarde des modifications mais lors de l'ouverture ultérieure il faut rappeler tous les presets d'usines car le tank g ne possèdent plus rien en mémoire.

*2025-08-02, version 1.3.24*

Esse app fica solicitando várias vezes durante o dia que conecte mesmo com o bluetooth desligado e o aplicativo fechado. A mensagem aparece na tela atrapalhando jogos ou qualquer coisa que esteja fazendo. Precisam arrumar isso. Só tem que solicitar conexão quando o aplicativo estiver aberto.

### 3/5 — Don't work

*2025-06-20, version 1.3.22*

Сначала все работало отлично, теперь ничего не сохраняется, неважно с приложения тел, с приложения на компьютере или без подключения, чисто на процессоре, просто каждый раз сбрасывается, каждый раз после включения заново приходится все настраивать.

### 1/5 — Connexion impossible

*2025-06-15, version 1.3.22*

Le blututh détecte la pedale mais l’application ne détecte rien

### 2/5 — All right, but...

*2025-06-12, version 1.3.22*

The app often stops and does not work. Every time you use it, you have to turn it on again after shutting it down.

### 1/5 — Ребят, ну вы чего..

*2026-06-21, version 3.5.2911*

Раньше все работало более менее, проблем явных не было… Сейчас все зависает. Открываешь вкладку в комьюнити любую дольше чем на 20 секунд и ты ее не закроешь. Приходиться выходить и заходить заново. Треш полнейший.

### 1/5 — Junk...

*2026-05-28, version 3.5.2615*

Tried for hours and it just doesn't work. Might have even bricked my new KE1. Stay away!

### 1/5 — Dañaron la app

*2026-04-27, version 3.4.2111*

En la última actualización cuando actualizo y refresco la lista de dispositivos bluetooth mi iPhone 16 pro Max no encuentra mi TankG y he verificado todo pero es imposible ojalá reparen eso

### 1/5 — It just doesn’t work

*2026-04-27, version 3.4.2111*

*2026-02-17, version 2.1.16*

Не видит устройство совсем

### 1/5 — Can't connect to any device

*2026-01-29, version 2.12.26*

I have tried every device, multiuple phones, ipads, computers you name it and I still cant connect via bluetooth. When I first got it everything worked fine, now nothing.

### 1/5 — ห่วยทั้งแอพ ห่วยทั้งสินค้า

*2025-10-21, version 1.3.29*

ห่วยมาก เชื่อมไม่ติดทุกอุปกรณ์ ทำทุกอย่างแล้ว แนะนำอย่าหาซื้อยี่ห้อนี้มาใช้นะ เสียดายเงิน

### 1/5 — App can’t find Tank B

*2025-10-09, version 1.3.28*

The M-EFCS app does not find Tank B. The iPhone, IOS 26, finds the Tank B and connects to it, but the app does not list the pedal. The BT icon on top right inside the app stays red always, even when the phone connects to pedal. Thus, M-EFCS has not use in my phone, or for this pedal, when out and about.

### 5/5 — 26 октября 2025 г.

*2025-10-26, version 1.10.21*

Всё работает, через приложение по блютус реагирует норм. Пока осваиваю, куда и как устанавливать новое? Ранее процессорами цифровыми не пользовался, ну ничего, разберемся! Русский язык добавьте!

### 5/5 — Landscape rotation

*2025-10-18, version 1.3.29*

Tolong tambahkan fitur tampilan layar ke rotasi landscape, untuk fitur yang lain dan fungsinya saya rasa memuaskan

### 5/5 — MIDI MAP for Snapshots

*2025-09-21, version 1.3.28*

### 5/5 — Ótimo app

Gostei bastante na minha Tank-G

### 5/5 — Good app

*2025-05-27, version 1.3.20*

Good app for tank g

### 5/5 — Добавить совместимость

*2025-05-20, version 1.3.13*

Приложение для MacOS не совместимо с системой версии 10.13 High Sierra. При установке пишет, что нужна версия 10.15. Очень обидно. Будет ли исправлена эта ситуация?

### 5/5 — Question

*2025-05-06, version 1.3.13*

Is there a setting which i can record songs using tank g from ios?

### 5/5 — kocret

*2025-04-24, version 1.3.13*

please add global EQ

### 5/5 — Great app, and the developers keep improving it.

*2025-04-04, version 1.3.1*

It allows you to add custom IRs to the MVAVE guitar pedal (the blue one with four buttons), as well as custom amp sims. It really makes the pedal useful. It’s easy to use, works well on iPad and iPhone. I have no idea why it has a low rating. 

If there was one minor thing I would like to see, a landscape view for iPad would be amazing, but that’s a niggle and not something I think is actually critical. In practice, I use this to set up my pedal, maybe once a month depending on what I’m doing, then don’t open the app again until I need to. Honestly great and super easy to use. The fact they added a community hub to download and share IRs and amp sims is also a total game changer. 

Thank you developers for adding all this amazing functionality!

### 5/5 — O Aplicativo é bom,Mas….

*2025-04-04, version 1.3.1*

Sugestão:Seria interessante,adicionar a função pra gente poder vê e saber,Quais amps ou ir,que estamos usando. Ou Seja os Nomes! 
Não só no Amps,ir, mas também nos outros efeitos da Tank G.
