On my Ibanez I have a ZR trem, which works great, but the socket for the arm must have worn away, because whenever I use the arm, it then "falls" to where to volume knob is, causing immense rattling, and making it awkward to access.

Without actually getting any new parts (tried it, the shop still hasn't got them in), what can I do to keep it in place?
Funny words.
I dunno if it'll allow use of the trem arm, but maybe shoivng a toothpick down there. Might do some damage though though.
