Dunlop Pegwinder 100SI — Manual String Winder with Bridge-Pin Notch
The Dunlop 100SI Pegwinder is a straightforward manual tool for speeding up routine string changes. Place its winding head over a compatible guitar tuning-machine button and rotate the handle to remove slack or wind a new string. Its notched head doubles as a bridge-pin puller on suitable steel-string acoustic guitars.

How Does It Compare with the 123SI and 124SI?
The 100SI is the basic hand-driven choice. The Dunlop 123SI Speedwinder adds a low-friction design and an ergonomic grip for repeated string changes, while the 124SI Bit Winder attaches to a compatible electric screwdriver. Unlike the 124SI, this model needs no power tool and gives direct manual control of winding speed.
Restringing Without Damaging the Instrument
Fully loosen the old string before pulling a bridge pin, hold the instrument safely, and avoid levering the notch against a delicate finish. When fitting new strings, bring tension up gradually and check the tuning with a reliable tuner. The 100SI is not a guitar tuner and cannot measure pitch. This listing is for the single peg-winding tool, not a restringing kit or a set of strings.
