I bought this trem arm for my Ibanez RG470AHZ as it didn't have the original one when I bought it. It fits perfectly well, as it should do and makes the bridge go up and the bridge go down as required. I've given it some serious abuse and it hasn't broken so it seems pretty solid and fits the bill. It's somewhat adjustable in that you can tighten the sleeve up to make the arm stiff or loose. It does squeak a bit and there is some play in it, but I thinks that's down to my trem unit itself.
