This lock string nut suits a wide range of headless bass guitars with a tremolo system or vibrato bridge. 



  1. Before installing the lock string nut, ensure that your bass guitar is in a stable position.
  1. If you are replacing an old nut, remove the existing nut first, by gently tapping it from the side until it loosens and can be lifted out.
  1. Place the lock string nut into the designated slot on the bass guitar's headstock. Ensure that it fits securely and aligns properly with the fretboard.
  1. Check that the screw holes on the lock string nut align with the corresponding holes on the headstock. 
  2. 5.Tighten the screws or bolts to securely fasten the lock string nut to the headstock.
  3. Once the lock string nut is securely installed, proceed with stringing the bass guitar. Insert the strings through the appropriate slots on the lock string nut and continue with the rest of the stringing process.


  1. Clean your bridge nut regularly to remove dirt, grime, and residue. Use a soft cloth or a mild cleaning solution specifically designed for instrument maintenance. Avoid using abrasive cleaners that could damage the finish or components of the bridge.
  1. Apply a small amount of lubricant, such as guitar or instrument-specific lubricant, to the frequently affected part of the nut such as the string holes. This helps to ensure smooth operation and prevent excess friction.
  1. Periodically inspect your but for any loose or worn-out parts. Tighten any loose screws or bolts as necessary. If you notice significant wear or damage, consider contacting a professional guitar technician for repairs or replacements.
  1. As much as possible, store your bass  in a suitable case or controlled environment when not in use.

Yes. A standard right hand guitar generally has its tuning machines on the left side (would need 6R Right Hand tuners), while the reverse headstock of a standard guitar would have a headstock that usually seen on a left hand guitar (tuners on the right side), so you should choose 6L Left Hand tuners.
