So, I borrowed an amp I was interested in buying (Vox Pathfinder 22W) from a friend and I really like the tones that come out. There's just one problem, when I pluck a note it starts to rattle after about a second, it then stops rattling a the tone continues a little softer.

I just switched on the amp again and now it doesn't do it anymore, but I'm afraid this isn't the end of it.

Any help? Could it be a loose wire or something easy to fix like that?

find out what's rattling and duct tape it.

likely places include handles, screws, and other things in the room

It's definitely from inside the amp. It's also doesn't really sound the rattling of an object, but more like a distorting signal (not like how distortion should sound).
