Can someone identify this guitar?

Another picture:

Apparently it was used by PM during the 1980's, but I haven't been able to find a good picture of the headstock, nor information about the guitar.

Also, I've found pictures of Pat with the same guitar BUT with a different headstock:

This one seems to have a bigger body:
Looks like the Malcolm Young signature. Gretch produces them now I believe.

Because I bend in such an unorthodox fashion; the notes kinda slide up and slide down...
It could be a Yamaha aswell. I've seen 70's-80's Yamaha's that look like that.
-2008 Gibson Les Paul Studio Cherry Sunburst w/ Alnico Pro II
-Marshall JCM2000 DSL 401
-Fender Hot Rod Deluxe
-Blackstar HT-1 mini stack
Malcolm's is a semi-hollow. Yamaha seems the best guess. Plus I know a lot of jazz guys play their guitars/basses, so +1 to Yamaha.
Yea its definitely a Yamaha, Pat Metheny (guy in the pics) played those for a while
