Fast response and amazing accuracy

After trying six free tuner apps and owning eight different clip on tuners I came to the realization I should of never strayed from the master. The Peterson app is fast, responsive, and more accurate then the ears God gave me. After using it on acoustic guitar, banjo, mandolin, dobro, upright bass, and a a friends Lyon and Healy concert harp I realize this is the tuner Ill keep for life. The external clip on mic/pickup is very helpful for noisey jams (only $12 at GuitarCenter.com).
