SCHALLER's locking tremolo unit, Floyd Rose licensed, Floyd Rose II, black. The block height at the back is 37mm. This is the model that was installed on the Charvel Fusion Custom. There is rust and signs of use due to aging, but I think it is still usable. ★Please note that the fixing screw hole on the back side of the 6th string saddle is stripped! Bushings, anchors, and locking nut are included. The adhesive remains on the back of the locking nut, so it should be clean if you peel it off. We are looking forward to your purchase if you will cherish it (・ω・)／
