BT8 - Fits 2008 and newer Fender American Standard Precision and Jazz Bass 4 string models.*Note: Be sure to check the housing on your detuner to make sure it matches this picture.
It works and does a fine job in the process. Easy to install. Go to Hipshot's webpage for the step by step installation and the most important part: the proper tuning technique. I put one of these on my American Deluxe Jazz bass and am ordering another for my American Standard P bass.
