The display shows the note being tuned and indicates whether the pitch is flat, sharp, or in tune. The needle will point to the center when the note is in tune. The LED indicators may also light up to show the tuning status.
Ensure that the input cable is securely connected and that the instrument's volume is turned up. If using the built-in microphone, make sure the tuner is close to the instrument and in a quiet environment.
The KORG GA Custom is designed to be powered by batteries and does not have a power adapter input. Make sure to keep spare batteries on hand for uninterrupted use.
