ok, so I got a new amp on friday, its an Ibanez TBX15R, it fell today and now the input jack wobbles around, but everything still works fine on it, can that cause any problems?
tighten it.

Yea as its something your gonna push and pull on alot. Wont be long and one day it pushes inside the amp. Many amps now the jacks are soldered to a PC board so if the jack comes out it tends to break the board. Which would be pretty much the end of the amp. Dont just turn the nut on the outside you need to be holding the back of the jack at the same time to prevent damage.
