my problem is the following. i've bought a used ibanez rg 320 fm a couple of weeks ago and i first noticed that the trem is looking very new because the pre-owner didn't use it too often as it seems. So i first tightened the arm torque with the two screws at the back of the sustain block. but after doing a couple of divebombs or something like that it's loose again. So i wanted to ask the question whether it is possible to replace the arm and it's socket with another one for example from Schaller or if there is any other way to make the arm don't get loose every second day.
