Drop tuning

[RG462]

Normally I wouldn't be too interested in drop tuning, but after listening to DT all day, I want to put one of my guitars in JPs, tuning. I believe he is in C standard but I'm not sure. I was trying to setup my rg to C but my tuner will not go that low. any suggestions?

octave. harmonic is at fret 12.

[RG462]

but see, my tuner doesn't have a C on it, or an F.

Use the MIDI off of Guitar Pro.

[RSVampire]

you should still be able to find a C or an F note on any of the other strings to use as a reference note.

[Kemono]

There is a 5th at fret 7.

A 5th from C is G.

You can also press fret 2 to get a D.

I'm sure you can find other ways if you try.
