The Floyd Rose Special double locking tremolo system offers great value for money, it uses 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. This is a full bridge system which includes adjustable posts and body bushings, tremolo arm, tremolo springs, claw and screws and string retainer bar. A locking nut is not included, these are available to purchase separately.
