Reply to Anyone know any sites for teardowns of controllers?

Hi All, I've just had a hercules dj control mp3 donated to me, the jog wheels feel pretty stiff, my mate who donated it said they've always been like that but I'd still like to see if it's just 6 or 7 years of crud build up.

So, does anyone know of any decent resources for taking these things apart? I know it's probably a handful of screws on the bottom but it's always good to read information before you dive into something.
