Why am I hearing distortion?
Likely the MIC GAIN knob is set too high. Ensure that the Input LED is green most of the time with only brief and rare peaks of red.
If you're experiencing distorted output on a Harmony Singer 2 pedal (which has automatic gain), please update your pedal with our VoiceSupport application. We have addressed an issue in Harmony Singer 2 where the pedal would randomly start distorting its output, it's fortunately fixed in the latest update.
