The best stomp box style tuner hands down. I wish I had tried this year's ago. I've been suffering with a TU-2 and it's imperfections for years. I recently built a home studio and while purchasing new gear I knew that I definitely needed a more accurate tuner and of course Peterson was the first and only name I thought of. Like they say, the rest is history. The Stomp Classic works exactly as described. Couldn't be more happy with it! I chose the Stomp Classic for the ease of being able to pass it around to other players and to carry it around the studio anywhere it may be needed with ease. Just pop a battery in it and go.
