i've got 4 different 12 string electric [solid and semi-hollow body]
and about 5 mandolins..

so i can vary and experiment with tunings as i like..

imho, tuning is a matter of personal taste and the ability of each individual instrument to stay in tune..

in the first instance i'll try to tune each couse exactly to precise matched pitch..

then leave the instrument to its own devices to see how far apart strings drift over a few days or weeks playing..

listening out for the point when any 'chorus' effect becomes so noticably out of tune..

that its time to bring it back under control again..


I'm sure other musicians would prefer to tune to their own personal preferences
of a starting point of a few cents out either way on each course to start off with a detuned chorus sound
