Floyd Rose
The slightly wider pivot screw spacing of the System 1 bridge needs a Floyd Rose licensed bridge design with one pivot screw cutaway that extends to the edge of the bridge allowing the Floyd Rose licensed bridge to mount onto the System 1 pivot screws. This configuration is most common in a "Floyd Rose Gotoh" bridge. Most Floyd Rose bridge designs have two pivot screw cutaways that are limited to the width of the pivot screws, and these will not fit the System 1 pivot screw spacing.
