Troubleshooting

No sound when the pedal is engaged.

Check the input and output connections. Ensure the pedal is receiving power (battery or power supply). Also, confirm the amplifier is on and the volume is up.

Weak or distorted sound.

Check the battery or power supply. Make sure the cables are connected securely. Adjust the Sustain, Tone, and Volume knobs to find the desired sound.
