My wife Elly and I recently went to see Pat Metheny and his Unity Band live in concert at Salford's Lowry Theatre. We were lucky enough to get almost front row tickets but were situated 6 feet away from Pat as the position of the seats were right in front of him. I had been following him since 1977 and I have always been a big fan.
The concert started with him playing a derivative of the guitar shown below.
I did a little research and found out that it was made by Linda Manzer a luthier based in Toronto see here. It gives me food for thought (not that I would be able to play it like Pat does) but I could have a go at making something similar.
Hmm a project maybe for the future.
