I have an Ibanez licensed Floyd Rose but the bar has never tightened down all the way and swings and wobbles. Following a tip on YouTube I bought this replacement from Schaller.
The bar looks like any one FR-bar, with a screw on top. This comes complete with bushel so you can replace the complete fitting including the screws and fitting on the underside of the tremolo bridge if you need too.
I only needed the bar, so unscrewing the fitting leaves you with a replacement bar, which fits perfectly and tightens correctly.
You may be able to get away with a cheaper solution buying the bar alone from another manufacturer at a cheaper price, but I saw differing reviews and didn't want to take the risk to solve this problem that I've been having for years. Fits perfectly!
