Hand toolFits standard pegsSetup

A string winder is a crank that fits over a tuning peg and turns it quickly, usually with a bridge-pin puller in the handle. Changing strings is the most frequent job on any guitar, and the winder is the difference between doing it before a gig and not.

Manual winders are cheap, quiet and never run out of battery. Powered winders are faster but can over-tension a string if used carelessly, and they are useless on a vintage peg that needs feel.

Where this fits: SetupSet relief, cut the nut, set the saddle and intonate. Setup turns a finished instrument into one that plays in tune and does not fight the player.

At this stage

The winder is used constantly — during setup, during intonation, and every time a string breaks. It is the most-used tool in the case.

Suits these instruments

  • All guitars and basses

Works with

  • Strings
  • Capo
  • Tuning pegs
  • Nut file set
Safety
  • Do not over-tension with a powered winder. A string that snaps at the peg whips across your hand and face.
  • Keep the crank clear of the headstock face so it does not scratch a finished instrument.

Working notes

  • Keep tension on the string while winding so the wraps seat tightly.
  • Leave two to three wraps on the peg — more causes tuning drift.
  • A winder with a pin puller saves carrying two tools.
  • Check the socket is not worn; a slipping winder chews the peg button.
