Shame on you if you're one of those players who lean their axe string-side down against their amp when they decide to take five! Chances are good that the drummer or somebody is going to walk across the stage, catch his foot in the cord, and the next thing you know, you're at the guitar shop with a decapitated Les Paul going in for neck-reattachment surgery.
Break down and get yourself a really good guitar stand like this Ultra 3442. It's got a nifty black finish, and your guitar will enjoy the comfort. It's an A-frame design that collapses, and there are no removable parts like those tubular stands with the surgical rubber things on it.
You owe it to yourself and to your guitar. Do the right thing. Buy a decent guitar stand (or two).
