Does what it says – BOSS Tuner Review

For the reviewers commenting on fixing the Mode button. If you read the in app help it states that the two buttons are not functional. It's basically just a picture of the hardware pedal. You'll notice the 1/4 jacks on the side. They don't work either. ;-) The tuner works just fine! Oh, and TC Polytune isn't on the App Store anymore that I can find FYI.
