what type of tremolo system does the ibanez rg550 20th anniversary remakes have? is it and Edge 3?
Are you kidding, no. Its an Original Edge. And before you ask if it has a Wizard II, its a Wizard neck. They are identical in specs to the originals (Which I'm assuming yours is?)
CJ Hit it right on. It's an Ibanez Edge trem, one of the best out there.
