How to string a guitar to get Pat Metheny's
" Baritone Nashville tuning "

The tuning from top to bottom goes A-E-C-G-D-A
with the middle two strings tuned an octave higher than the rest. This means that in terms of chord shapes it is just like conventional tuning but the voicing of chords is much different and obviously the overall tonality is lower and kind of wider. It's great fun to play with and definitely not just for jazzers - blues sounds great in this tuning (as long as you can leave out all your usual lead runs as they can sound a bit odd when you jump an octave - but it's quite a good thing sometimes to have to rethink the way you play) To hear a quick sample of me doing some fingerstyle noodling with this tuning go here.

These are the string gauges I used to do my conversion.
from top to bottom.
A = 16
E = 28 wound
C = 14
G = 26 wound
D = 56 wound
A = 80 - this is an A bass string which I converted by removing the bass ballend and replacing it with a guitar one, and also removing some of the wrap at the machine head end in order to get the string through a guitar machine post
This setup is for an acoustic guitar and I just found that the bass string gave a better sound - you could use a heavy guitar string such as those in a 7string or baritone set particularly on electric guitar.
- Now the tricky bit ;

You need to enlarge the nut slots for the outside four strings (you could do this yourself but it's a little bit hazardous and you might want to entrust this job to your local luthier)
