### 1/5 — No audiobus and iaa doesn't work

*2017-01-26*

I can't get this to work as an iaa effect on my iPad Pro. When looking at settings and then trying adjust the input setting I get a "This device is not support" error message (no, not a typo on my part). With no audiobus support either there is no way to hear how it sounds as an effect. I haven't tried with direct in though.

### 1/5 — Not very compatible

*2016-11-17*

Garageband uses way too much memory.  Without Audiobus compatibility this app is pretty useless to me.

### 1/5 — I hate ads

*2016-09-23*

Insta-delete.

### 4/5 — Thnx for the free IAP offer

*2016-08-26*

Glad you give us a way to test out your fx for free.

### 2/5 — Can't restore

*2016-08-24*

After going through the tedious process of entering my password etc for EVERY item, when I reboot the app as asked, it shows them as purchased, but not available. You guys beta test this??

### 2/5 — Effects seem very garbled and difficult to control

*2016-08-24*

Effects don't work very well on a guitar. Sounds kinda garbled. Guess that's not a big deal if you want really glitchey sounds but it mostly sounds like a bad connection. Maybe im just not understanding what the point is

### 4/5 — light and useful

*2016-08-21*

guitar effects in a small size app, unlike the humongous size of the major players.
if this was AU instead of just IAA,,,
