The Cuda Winder Guitar String Winder - Ocean Blue
The Cuda Winder is the patented string measurement gauge incorporated into the handle. The notches that correspond to each string help you make a visible mark in the string, giving you a repeatable process for measuring its optimal length. Measuring each string to the optimal length means your instrument will stay in tune longer and you'll experience longer string life.
The current model of the Cuda is compatible with inline 6-string electric guitars and 3x3 6 string acoustic and electric guitars.
