Wittner PGCWS1 Finetune Single Cello Peg, 12.5 mm, 4/4 - 3/4

Wittner Finetune Single Cello Peg, 12.5 mm

The Wittner Finetune Single Cello Peg in the 12.5 mm option provides geared tuning for the selected 4/4 - 3/4 size designation. Its internal reduction mechanism allows controlled pitch adjustments by turning the peg head. Composite and light alloy construction supports a design whose fitted shaft stays stationary in the pegbox during tuning.

Cellists and instrument repair specialists can select this individual component when replacing one peg or planning a measured tuning upgrade. For a single cello peg replacement, the diameter at the ring and shaft taper help determine fit. This geared tuning peg for cello suits players seeking finer adjustment at the peg head. Instrument size alone does not establish compatibility; the existing peg holes also require assessment.

Wittner manufactures its Finetune pegs in Germany and provides fitting instructions for installation. The tapered body fits into a prepared peg hole without glue, while the rotating central section carries the string. A luthier, a specialist who builds and repairs string instruments, can evaluate the pegbox and fit the component. Correct string placement and careful hole preparation support the intended tuning operation.
