Wittner PGCWM112 Finetune Single Cello Peg, 12 mm, 1/2 - 1/4

Wittner Finetune Single Cello Peg, 12 mm

The Wittner Finetune Single Cello Peg in the 12 mm size provides geared pitch adjustment for 1/2 - 1/4 cellos. Its internal reduction mechanism lets players tune by turning the peg head while the fitted outer shaft remains stationary. This individual component supports replacement of one peg when its dimensions suit the instrument's pegbox.

Cellists, teachers, and repair specialists can select this option when sourcing a single replacement tuning peg for a smaller instrument. For a fractional cello tuning upgrade, the diameter at the ring and shaft taper help establish fit. Fine adjustment at the head supports controlled pitch changes during practice and preparation. A measured pegbox assessment remains essential when choosing a geared peg for cello maintenance.

Wittner manufactures its Finetune pegs in Germany and provides detailed fitting guidance. The composite body fits into 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 hole dimensions and position the peg correctly. Proper fitting considers the existing pegbox, string clearance, and installation depth alongside the instrument's stated size.
