GOTOH UPT-UB8-CW The UPT is suitable for ukuleles with a head thickness of 10-12mm, depending on the thickness of the ukulele head to be installed. While maintaining a similar look to traditional friction pegs, a 1:4 gear ratio is achieved by adopting a planetary gear mechanism. You can experience smooth feeling and stable tuning, reducing the risk of reverse rotation without tightening the button like conventional products. These pegs are used on top ukuleles around the world, such as KAMAKA.
