For all guitarists, but for all the other musicians (chromatic tuning) is the essential tuner to lug everywhere: it is very small, extremely practical and readable regardless of the light. Above all, it is incredibly precise and absolutely "deaf" to all the surrounding noise as "hears" the sound but no captures its vibration on the instrument itself. A dream when, at the choice, the baby screams of neighbors, the birds burst or other musicians tune / heat up at the same time! Icing on the cake: a small price for absolute reliability (it's a Korg ...)
