ibanez fans will tell you that the TRS trem is to be avoided. it's a budget trem the company equips on their enty level guitars. the TRS & Edge/ Lo-pro edge are discontinued WEF 2003. if you want zero-point return accuracy, the new ZR bridge (check out ibanez's 2003 S-series offerings) would make you happy but be warned that this trem adds weight to your guitar.
