Detail 01
String-lock screw engagement
The tool is placed over the string-lock screw before the saddle is adjusted.

Independent shopping perspective
Set intonation on an Original Floyd Rose tremolo with direct control over saddle movement. The Key slips over the string-lock screw; once the saddle mounting screw is loosened, it lets you move the saddle by hand to place it accurately. It is a focused maintenance tool for players adjusting saddle position rather than a general-purpose guitar tool.
