Great video on changing classical guitar strings.

Here you are. Like one of the comments says, skip to around 7:30 for the good stuff.

While we're on the subject of classicals, anyone recommend some good pedals? I've been playing classical guitar for a long long time and I've not thought to use these. Done a little bit of online research but maybe you lovely people have some personal recommendations.
