Once all the strings are displayed, you can easily adjust and fine tune each string, making tuning a speedy and stress-free process. The guitar-specificAW-OTG-POLY incorporates everything you would normally expect from a normal tuner, but also includes a chord finder function that’s incredibly useful for individual practice.

This function allows you to know quickly and accurately the chord being played, allowing you to visually follow and recognize any chord progression in real time. The chord finder will also work when using a capo up until the 7th fret. This incredibly versatile tuner will adapt to various performing environments to always offer the best performance.
