Tuning a guitar to sound like a mandolin

Or; fifth tune and Capo
A mandolin is tuned in fifths. So to imitate that sound we'll tune the guitar to fifths. (Alternate tunings discussed here) And even though mandolins are tuned in unison notes, we'll keep the octave differences on the D and G courses. This tuning requires allot less change that tuning it exactly as a mandolin is tuned.

If you do fith tuning;

dD stays the same
gG goes to aA
BB goes EE
EE goes BB

(If anyone is scared of the tension put on the strings by this lower all strings by a half step or more, then capo higher)

If we put a capo on the 5th fret we can even have a gGdDAAEE exactly like a mandolin!
