Wittner PGVWS1 Finetune Single Violin Peg, 7.8 mm, 4/4 - 3/4

Wittner Finetune Single Violin Peg, 7.8 mm

The Wittner Finetune Single Violin Peg in the 7.8 mm size provides geared pitch adjustment for 4/4 - 3/4 violins. Turning the head adjusts the string through a rotating central section while the fitted outer shaft stays stationary. This individual component supports replacement when its diameter and taper match the instrument's pegbox.

Violinists and repair specialists can select this option when sourcing a single replacement tuning peg or planning an instrument upgrade. For a geared violin peg replacement, the diameter at the ring and shaft taper help establish fit. The individual format suits maintenance of one tuning position. A measured assessment supports a violin tuning hardware upgrade because nominal instrument size alone does not determine existing peg-hole dimensions.

Wittner manufactures its Finetune pegs in Germany and provides fitting instructions for violin installations. The composite body seats in a prepared tapered hole, with the string wound onto the rotating central section. A luthier, a specialist who builds and repairs string instruments, can assess installation depth and string clearance. Correct positioning allows the moving section to carry the string while the surrounding shaft remains fixed.
