To address the open tuning community directly, Peterson has come up with custom Sweeteners specifically for open tunings. You don't have to settle with "good enough" when tuning your instrument. Simply find the Dobro sweetener you desire in the key of A,G or D, and then tune up quickly and accurately. Spend more time making your guitar sing instead of singing the tuning blues.
Thanks to Peterson's unrivaled accuracy, and with the help of players from all over the world we created some new tuning presets for open tunings. The Dobro® Sweeteners are available in pure and half tempered for your open tuning preferences. These Sweeteners are a completely unique feature of Peterson's Virtual Strobe Tuners, which also offer Sweeteners for bass, acoustic guitar, and more.
