yeah really... like I said in the video... if you take em off one at a time, all you keep doing is transfering all the crap from the old strings to the new ones.

I've been reading for years about so-called experts who say you have to take the strings off one at a time or 'the neck will warp'.
Yet whenever you ask anybody if they've actually seen it happen or where they heard that rumour they don't have a clue.

It's one of those old wives tales like 'the correct way to wind your guitar cord'.
Whatever you do, don't wind it around your thumb and elbow or you'll break the wires inside.
Anybody who says that I can prove without a doubt that I can wind my guitar cords that way and it's safer than doing it with your fingers.

sorry... hard to explain without a video
