When I wrote Truss Rods Made Easy, I mentioned that Ovation, bowl-back
guitars, without a regular sound hole, had to have their truss rods
adjusted through an access port around the back. I didn't have a guitar
handy for a photo, though, and pretty much forgot about it until a couple
of weeks ago when I was working on one.
I took a quick video.
And, since I'm essentially an excitable child, I felt the journey inside
was just cry...
