The Hipshot BT7 Xtender allows you to instantly drop the tuning of your bass' low string and then back again with the flip of a lever. The BT7 is a direct replacement for the tuners featured on many made in Mexico Fender basses and the Hipshot HB7 bass tuner. The lever can drop a major 2nd (E down to D) and if your strings have standard thickness cores you can go as low as a 4th (E down to B). The tuner itself features a 1:27 gear ratio for tuning up accurately and an adjustable tension nylon bearing system for the worm gear. The 4 included screws fix the drop tuner backplate to the back of the headstock and the knurled push fit bushing secures the string post on the front of the headstock.
