I picked up a Vidami Blue a few weeks ago, and it instantly changed how I practice guitar each day. The hands-free bluetooth pedal has 3 modes that have helped me out in a major way: its page turning mode works brilliantly for flipping pages in a number of iPhone and iPad apps, not to mention the ability to scroll through tabs online.
You can use it as a YouTube control device, where you can play, pause, go forward or backwards in time on the video, make loops, and even slow down the video, while retaining the original pitch!
And if you record your guitar, it works with a number of DAWs as a DAW controller, helping to play/pause, record, turn on your metronome and more.
I think this pedal is a no brainer to have on any guitarist's board. Check out my full video walk through of the pedal below.
