Re: Tremolo Bridge "what fits where" Reference Chart (master reference thread)
The larger the sample size the more variation you'll find. But you did file (modify) it, even slightly. That counts for something. Maybe this was possible (and paint messy) because the router bit was worn out (cost savings) thus imprecisely cutting (tearing) away a larger trem route than intended (in the cheap & wet wood)? Tons of possible alibis. But you have a 1mm stud spacing difference and one knife edge flat thus some wiggle room.
Still, the best answer to all things is the simplest one. From roughly 2003-06 the 555 was designed (programmed & setup to route) the body for the new EP2. Not an Edge, not an Edge3 (that came in 07). This goes for all the other Ibanez guitars routed for EP/EP2.
