The KORG GA-1 is pre-calibrated at the factory, and there is no manual calibration feature. Ensure the tuner is in a stable environment and replace the batteries if tuning seems off.
Check the battery compartment to ensure that the batteries are inserted correctly and have sufficient charge. If the problem persists, try replacing the batteries with new ones.
Yes, while the KORG GA-1 is optimized for guitar and bass, it can tune other instruments by matching the closest note and adjusting accordingly.
Press the 'CALIB' button repeatedly to cycle through the available reference pitches (from 430Hz to 450Hz) until you reach the desired setting.
Ensure that your guitar's volume is turned up and that the cable is properly connected. If using the built-in microphone, make sure the tuner is close to the sound source in a quiet environment.
Turn off the tuner when not in use and remove the batteries if it will be stored for an extended period. Use high-quality alkaline batteries for longer life.
Press the 'CALIB' button once, and the current calibration setting will be shown on the display for a few seconds.
Use a soft, dry cloth to clean the exterior of the tuner. Avoid using any solvents or abrasive materials that could damage the surface.
Press the 'MODE' button to toggle between Guitar and Bass tuning modes. The display will indicate the selected mode.
Check the calibration setting to ensure it matches the standard 440Hz, and make sure there is no interference from other electronic devices.
