Using this bass peg winder is a breeze. Just place the winder on the tuning peg of your bass and turn the handle to wind or unwind the string. The built - in string stretcher can be used by gently pulling the string through it to stretch it out. When using, make sure the winder is firmly attached to the peg to avoid slippage. After use, clean it with a dry cloth to keep it in good condition. Store it in a dry place to prevent rust or damage. This winder is a great addition to your bass setup, making string changes and tuning much easier.
