I enjoy the Peterson Strobostomp HD pedal very much. It is accurate and easy to understand. The other features, such as the sweetened tunings for pedal steel guitar are a plus too. I originally bought it in order to have a more accurate tuning device in order to intonate my guitars, but when I learned of the other features like the one listed above, I was extremely pleased. It's met my expectations and I hope to buy more of these products in the future. I already have one of my friends sold on the idea of buying his own when he saw how mine worked. Thanks for making products like these that help a musician get closer to a perfect tuning every time.
