This is an arm for an Ibanez tremolo bridge. It's the type that is fixed simply by inserting it. I have confirmed on my own guitar that it can be used with tremolos that use the Zero Point System (ZPS3). Currently, Soundhouse sells this in Cosmo Black, but this one is chrome color. While there is some clouding on the plating, there are no plating剥がれ (peeling) or rust. Due to the nature of the product, please understand that returns are not accepted for reasons such as incompatibility after purchase.
