For decades Schaller have manufactured the Original Floyd Rose double locking tremolo, now it is also available from them directly with replaceable hardened steel knife edges. Double locking tremolos provide the ultimate tuning stability through the combination of the locking nut, locking saddles and fine tuners. This bridge features steel saddles for clarity and response and a brass tremolo block for sustain. The tension holding the tremolo arm can be adjusted via the screw down nut. The locking nut is supplied with the tremolo and you have the choice between the R2 and R3 size and it 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. We also stock this in two depths of tremolo block to allow you to select the right size brass block for your guitar's body thickness. 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.
