I find that Double C tuning works well for instrumentals but is not so great for chordal back-ups. I usually use Open C tuning for vocals or when I'm in a situation that requires me to use a lot of backup chords.
Thanks... Mike
My opinion page addressing inquiries concerning clawhammer technique.
The open strings in Double C Tuning spell out a a "C add 2" chord. This is a chord which has no third (which determines if it's a "major" or "minor" chord). This "no third" tuning is what makes Double C so versatile, it can handle major, minor, or model scales easily!
