The JHG Tuner is a useful tool for guitar players to tune their instruments. It offers two tuning options: "Full Tune" and "Quick Tune".

When using the "Full Tune" feature, you play each string separately on your guitar. The tuner will automatically analyze the sound and provide feedback on whether each string is in tune or not. This can be helpful in quickly identifying which string needs adjustment.

On the other hand, the "Quick Tune" option allows you to listen to the sound of each string and get a sense of what it should sound like when properly tuned. By hearing the string's sound through the Quick Tune feature, you can make adjustments to your tuning by ear.

Both features of the JHG Tuner can be beneficial in helping guitar players achieve accurate tuning for their guitar.
