What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Holds the E string down behind the nut. Increases break angle so the string seats firmly and stops rattling in the slot.
Detail 02
Drilled and positioned for vintage-style Fender bass headstocks. Modern and import headstocks may place the hole elsewhere.
Detail 03
Fastens to the headstock face with a single screw. An existing hole makes this a five-minute job.
Detail 04
Affects string angle only, not intonation or scale length. Too much downforce can bind the string in the nut slot.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It presses the E string down behind the nut so the string sits tightly in its slot. Without it the string can buzz or pop out during hard playing.
Not necessarily. This is cut for vintage-style headstocks. Compare the hole position and footprint on your bass before ordering.
Loosen or remove the E string at minimum. Full removal makes access easier and avoids scratching the headstock.
No. It only changes the string's angle behind the nut, which affects seating and rattle, not pitch or intonation.
