Machinehead Designs for Composite Chordophones

From “Inside the Bass¨ in The Bass Handbook

Also known as […] tuning pegs, they keep your bass in tune and secure the string in place. Think of them as winches working on the worm gear principle. Two common types are found: open-geared and enclosed.

These two types of machineheads or tuning pegs (refer to 20241215165631-Composite_Chordophone_Hardware_Components), open-geared and enclosed, can be explained thusly (Ashton 2005, 23):

  • Open-geared machineheads / tuning pegs “is the oldest design,¨ and is “easy to use because of their large ‘buttons´.¨ However, the quality of this type of machinehead or tuning peg can vary greatly. Certain instances of open-gear machineheads or tuning pegs can be very useful for drop-tuning a bass guitar (though this could require adjustment of the string gauge to maintain string tension).
  • Enclosed machineheads / tuning pegs offer a “gear wheel and worm shaft¨ that “are sealed into a maintenance free housing.¨ They are usually “smaller and more compact than the traditional open gear styles,¨ affecting balance and making it “a sensible upgrade to a bass.¨

- Slightly less ease of use
- Bigger and less compact
- Less balanced
- Allows for drop-tuning to exact pitch
- Slightly more ease of use
