### 5/5 — This App has helped my career so much.

*2023-09-12, version 1.0.6*

I live this app and so thankful it still works after all these years. Hope the support somehow stays alive.

### 1/5 — Doesn’t work

*2021-10-14, version 1.0.6*

I download the app, I clicked around on all the buttons and nothing happened. I deleted the app.

### 1/5 — Nope

*2021-09-03, version 1.0.6*

It doesn’t work with IOS14.7.1. Sad. Please fix it so I can thrive as a guitarist and make my ancestors proud.

### 1/5 — Why would you release this software with all these bugs and things that need to be fixed

*2021-02-10, version 1.0.6*

You need to have every parameter adjustable and be able to be edited on this system itself that would be VMRTHR1011 or the wireless models either or you should be able to just having at least more than one to how about three how about four affects at the same time that something that shouldn’t really be that difficult this is Yamaha correct overall not too impressed you guys are leaders you make great guitars and instruments fix this

### 3/5 — Does this still work?

*2021-01-16, version 1.0.6*

I just bought a new THR amp and I want to practice with this app. This app seems to not be working with iOS 14 or maybe I am not using it correctly as there isn’t any instruction. Please update the app. I think it would be very useful if it works.

### 5/5 — Love it

*2020-08-04, version 1.0.6*

Awesome little app for learning new songs on guitar. Really cool how you can slow down the song but not change the pitch. Also, I absolutely love how it lets you isolate the guitar in a track to really hear what’s going on. Just needs some instructions!

### 3/5 — Hmmm

*2020-01-22, version 1.0.6*

I don’t get it? The only thing I do dig is the repeat function! Everything else in my honest opinion is kinda worthless! AND I LOVE MY THR AMPS!

### 5/5 — Works great again!

*2016-11-02, version 1.0.5*

Works great with ios10.

### 1/5 — Doesn't work...

*2016-06-17, version 1.0.5*

I recently bought a THR10, and love the amp! I was really excited when I heard about this app; looking forward to using some of its "abilities" to complement the use of the outstanding amp.  Well, currently, it's "abilities" amount to loading on my 6s, and an "on/off" switch that toggles.  It will not recognize any songs in my phone's memory; no music, no play...  Currently running iOS 9.3.2.  Have read rave reviews from users of less advanced phones and software versions-- C'mon guys, you can do better than this...

### 1/5 — Broken App, disappointed

*2016-03-01, version 1.0.4*

This app worked fine on my 4s, now it won't play songs on my 6s. Pretty disappointing that a company like Yamaha can't get this right.
