How To Tune
Pluck and Check
Choose your tuning in All tunings. Start with String 1 (thinnest string). Pluck it and watch the tuner respond. Aim for the middle line, which indicates perfect tuning.
Adjust the Peg
If the pitch is too low, gently tighten the string; if it’s too high, gently loosen it. Repeat until the tuner shows the middle line and you hear the success sound.
Tune All Strings
Move through each string (1 to 6), tuning them in order. Recheck all strings after tuning, as adjustments may affect others.
Tuning Tips
Trace the String
Follow the string to its tuning peg to ensure you’re turning the correct one.
Avoid String Snapping
If turning the peg doesn't change the tuner reading, double-check you’re adjusting the right peg. Turning the wrong one may cause a string to snap.

When should I tune my guitar?
Guitar strings naturally shift pitch due to temperature, humidity, and use. Regular tuning ensures the best sound. If your guitar frequently goes out of tune, consider a professional check-up to ensure it's properly set up.
