Note names won’t tune your guitar.
Knowing the strings should read D G D G B D is the easy half. Landing each frequency — and knowing whether you are nine cents flat or three — is the half that needs an ear or an instrument.
1
Open Dial and play a string
It listens as soon as you play. Nothing to press.
2
Turn each peg until the needle centres
Three strings move: both E strings drop to D, and the fifth string drops to G.
3
Check the remaining strings
Changing tension on one string shifts the neck slightly. The rest usually need a nudge.

What Open G is for
The blues and slide tuning — and Keith Richards' home for fifty years of Stones riffs. Barre one fret and you have a full major chord; a slide does the rest. Delta players tuned here long before it was electric.
