This could be useful for those of you who have Edge (Pro) equipped Ibanez. The idea of replaceable washers is nice because any material will wear out after some time, so why not make it replaceable. The only problem is that they can hold tight for two weeks before wearing enough that the trem arm doesn’t stay in place any more.

I tried a couple of things, none of which worked, before finding the best solution on the web. The idea is to use heat to harden the washers and expand them a bit. 5 seconds over a cigarette lighter flame while slowly rotating the arm did the trick for mine. Two years later and I still haven’t replaced them.
