Turbo Tune™ is a cleverly designed string-winding crank that also pulls apart: use it by hand or with your cordless screwdriver. Its versatile socket fits practically any guitar or bass tuner knob, to make string changing fast and easy. The handle is conveniently notched for pulling stubborn bridge pins, too.
Turbo Tune is made of dense, highly durable plastic, with a 1/4" steel hex stem. It's also available in a special glow-in-the-dark model that comes to the rescue on dimly-lit concert stages.
