NOTE INDICATER LED
A
B
C
D
These LEDs indicate the note of the strings you are playing. When tuning sharp or flat notes such as G#, both
the G indicator and the # indicator will light up. If the note shown on the note indicator LED is different from the
one you wish, try tightening or loosening the string until the correct LED lights up. Be careful not to tighten the
strings too much (over tune) as the strings may break. When in doubt, it is better to tune down and loosen the
strings and then tune back up to find the desired pitch.
TUNING GUIDE LED
When the string is in tune, the green LED in the middle will light up. If the pitch of the string is flat, the red LED
on the left will light up. If the pitch of the string is sharp, the red LED on the right will light.
