If the tuner does not show the pitch, the volume may be too low. Adjust the [VOLUME] knob to increase the volume.
- When tuning a bass guitar, in addition to raising the volume, set the [TYPE] switch to "CLEAN" and turn on the [VARIATION] button (the VARIATION indicator should light up).
- If you’re having trouble tuning an acoustic guitar, set the [VARIATION] button to OFF (the indicator will go dark).
