Schaller Tremolo Locking Nut Right R2 Black Chrome 20040402
The strings sit just as firmly, but there are no sharp edges that could potentially cause string breakage. Suitable for all common string gauges. Radius is 10".
Essentially, special studs are used to attach the tremolo, together with their own inserts. These have a fine thread. For special applications, we also supply studs with threads which can be screwed directly into the wooden body (i.e. without inserts).
