Mini geared individual – a mini version of the Profile-geared machines was designed for guitars that require a smaller machine because of their construction. The mini machines are packaged in a set of 6-left for 6-in-line installation. Lower in weight yet providing the same precision 14 to 1 gear ratio. Mounting screws are eliminated by the use of sharp anchor spurs on the underside and the pressure from the threaded hex bushing.
