It seems the developers went through a great amount of effort to block you from connecting the device without turning on "precise" location. Which isn't necessary for a guitar device. If you really need region data, approximate location is fine. You do not need my precise location. One thing people seem confused about is the Bluetooth. It's pairing to your phone for app controls. You still need to use the aux cable for your headphones. Other than that, it has a lot of options for sound.

I had problems with the app until I finally figured it out. When you start the app it shows the intelligent guitar. You have to scroll with your fingers to the left to get the FX-20. The two dots below the images on most applications allow you to move from one to the other but it doesn't on this one. I've used the FX-20 for about 4 weeks now. I consider it to be the future. The thing is absolutely amazing, and the amp simulations sound better than some of the amps that I have that's on the app.

It's good. Never had a single issue with it. I bought the FX20 cause it was compatible with this app. I'm really glad I didn't read these reviews before buying it.
