Wittner PGCWL1 Finetune Single Cello Peg, 15.5 mm, 4/4 - 3/4

Wittner Finetune Single Cello Peg, 15.5 mm

The Wittner Finetune Single Cello Peg in the 15.5 mm option provides geared pitch adjustment for the selected 4/4 - 3/4 size designation. Players tune through the peg head while the fitted outer shaft remains stationary. This individual component supports replacement of one tuning peg when its diameter and taper suit the instrument's pegbox.

Cellists and repair specialists can select this option when sourcing a single replacement tuning peg or planning a measured instrument upgrade. For a geared cello peg replacement, the diameter at the ring and shaft taper help establish fit. The rotating central section carries the string during adjustment. A pegbox assessment remains essential for a cello tuning hardware upgrade because nominal instrument size does not establish existing hole dimensions.

Wittner manufactures its Finetune pegs in Germany and provides installation guidance for cello fittings. The composite body seats in a prepared tapered hole, with the moving string-bearing section positioned at the pegbox's inner edge. A luthier, a specialist who builds and repairs string instruments, can assess installation depth and string clearance. Correct fitting allows the central section to rotate while the surrounding shaft stays fixed.
