Tuning tips

  • Tune in a quiet room and hold the phone near the guitar.
  • Pluck one string at a time and let it ring until the needle settles.
  • If the reading jumps, turn AUTO off and tap the string you are tuning.
  • If PegTune shows “Microphone access needed”, allow it in Settings → PegTune.
