I was looking for a small tuner that wouldn’t be too noticeable on the headstock and could also fit in a guitar case without needing to be removed. In this regard, the D’Addario tuner deserves the highest rating. However, the device sometimes freezes and doesn’t always display the correct note. For example, instead of showing G, it might display B, which is frustrating. Next time, I’ll go for a more expensive product or a pedal tuner.
