This is a 7 string version of the Floyd Rose Special double locking tremolo system, complete with locking nut. The special series tremolos offer great value for money, they use a steel base plate for hard wearing knife edges, the same as the Floyd Rose Original, but utilises zinc alloy saddles and sustain block to reduce the price. Double locking tremolos provide the ultimate tuning stability through the combination of the locking nut, locking saddles and fine tuners allowing extended and wild use of the wammy bar without going out of tune. The tension holding the tremolo arm can be adjusted via the screw down nut. The 7 string locking nut supplied with the tremolo comes with screws for mounting from the front of the neck and also hex/allen head bolts for mounting from the back of the neck depending on which is required. This is a full bridge system which includes adjustable posts and body bushings, tremolo arm, tremolo springs, claw and screws, string retainer bar and locking nut.
