How to tune your 7-String Guitar

  1. Click Start Tuning above and allow microphone access.
  2. Play one string (or note) at a time, close to the microphone.
  3. The tuner shows the nearest target note and how many cents you are off.
  4. Tighten to raise the pitch, loosen to lower it, until the display turns green.

Need a different tuning? Use the tuning selector above the display — every preset is free. You can also lock any note by clicking it, which is handy when a string is far from its target.
