I've been a Neil Young fan since I saw him in my first concert back in late 60's with Buffalo Springfield... seen him maybe 10 times since including Rust Never Sleeps tour at the Cow Palace in SF.. I NEVER noticed this unique set up nor known of it.. thank you very much for posting this. He's been the main influence in most of my playing acoustically and electrically and I've probably mimicked him way too much. :o
