Nailed it!The boss katana go is my favorite piece of gear now. I use it for guitar and bass. I play along with music streaming on my phone over a Bluetooth connection while walking around outside. It also works as an audio interface when plugged into newer iPhones via usb-c connection. So much tech in a small inexpensive package.

Bluetooth aspect not very functionalWould not recommend getting this product or app not easy to set up and have to do setup multiple times just to get it to work and you have to do it all over again every time you wana use it needs serious work

Needs a better UIThe only thing holding it back for me is the UI (user interface) it needs more graphics (buttons, knobs, switches). Just showing numbers isn’t enough specially for new guitarists. This app acts as if everyone knows what all these settings are. Other than that this is a great app to go along with the Boss Katana Go.

nahThe app is absolutely fantastic. You can literally stream backing tracks from your phone to the amp!!! If you know how to use a phone, you can get around the app. All I will say: sounds slightly less better than fenders Mustang headphone amp.

Doesn’t rotateThe app is great for
Mix and setting the GO but the app it’s self does not rotate when in landscape mode. If they update the app to do so my rating would be higher.

Ok-Could be much better with small tweaks!The biggest pain is always having to sign in because the session has ended. I also hate that my library disappears randomly!
