Ahhh the embarrassment of live shows... I LOVE IT!!! I was playing a show once. we were a 5 piece and in the middle ofthe show the other guitarists amp blew. He kept puttin goff getting a new one... well that night made him wish he hadn't. We ended up being able to borrow an amp from a bud in the audience. If he hadn't of been there we definately would have had to cut the show short.
The cable looped through the strap was one of the first things I learned to do. Eventually I saved and got a wireless so I didn't have to worry about the cable at all. That was killer.
That which you can not cure,
you must endure!
