While looking at yamaha guitars because of the SA-2000 thread, I found this on Yamaha's website.
Roof Test
I'm sure this is not the only guitar in the world able to pass this test, but how many have tried?
Now I know which gutiar I am gonna use for that rooftop gig. When the police come and kick us off so fast that I don't get a chance to grab my guitar, I'll know that even though it may take a month to sneek back onto the roof to get my guitar, it will be in perfectly playable condition after a string change.
