Schaller FR Tremolo Black 13020437.02

Schaller’s long-term experience with the production of double locking tremolos has gone into the development of this identical tremolo. Exchangeable knife edges made of hardened steel and cast steel saddles, combined with a solid tremolo block provide perfect sound transmission and an extremely long sustain.

The tremolo radius is 12″, the radius of the nut element is 10″ for the R2- or R3-Nut. This is related to the taper of the fingerboard and has, in all previous experience, resulted in optimal playing properties. 12″ and 10″ measurements are the most frequently used sizes in the guitar industry.

Special studs with additional inserts are used to mount the tremolo onto the instrument. The inserts have a fine thread. Schaller also supply studs with threads which enable the studs to be specify screwed into the wood body of the instrument directly, i.e. without inserts.

The back of the string lock inserts is numbered with 0,1 and 2. 0 is for the D and G strings, 1 is for the A and B strings and the number 2 is for both E strings. 

You can simply pull out the knife edges with a pliers and push the new ones into the insertion slot.
