wobbly master pot - oh no

[queglay]

hey everyone! this is my first post.

i just picked up a virus c from ebay. the master volume pot on it is wobbly and feels like its about to break off!

the seller forgot to mention this to me. either that or he packed it unsuitably.

there is a sticker on the back preventing me from opening it up to check what kind of physical damage there is. i know that this thing wont have any kind of warranty on it anyway, so is there any other reason i shouldn't take the sticker off and open it up?
im hoing i can fasten the pot down more securely and prevent it from getting worse.

cheers for any help!
