The SynchroniZR tremolo bridge Red copyright sprite

The SynchroniZR is a synchronized non-locking tremolo bridge made by Ibanez and mostly sourced on SV series guitars, as well as a few RG series models. Inspired by the ZR (Zero Resistance) tremolo before it, the SynchroniZR relies on ball-bearings as pivots instead of the usual tremolo knifes.

The Zero Point System used conjointly with this tremolo bridge is the ZPS-FX.

The SynchoniZR was released on the market in 2008, along with the ZR2 with ZPS3 and the Edge Zero with ZPS3 as well.
