Note names won’t tune your guitar.
Knowing the strings should read D A 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
Both E strings drop a whole step to D: 73.4 Hz on the sixth, 293.7 Hz on the first.
3
Check the remaining strings
Changing tension on one string shifts the neck slightly. The rest usually need a nudge.

What Double Drop D is for
Neil Young's tuning — "Cinnamon Girl", "Cortez the Killer". You get Drop D's one-finger power on the bottom with a chiming octave D on top, and the middle of the neck still plays like standard.
