What is left and what is right mechanics?

  1. Look at the mechanics from the front.
  2. The front is where you can see the Guitar Monkey logo.
  3. If the neck of the machine head (marked in red) is on the left side, it is a left machine head (bass side).
  4. If the neck of the machine head (marked in red) is on the right side, it is a right machine head (treble side).

Why bass or treble side?

It's simple: imagine a 3+3 headstock like you find on classic single-cut guitars. Here you have 3 left-hand machine heads to which the bass strings are attached, which is why left-hand machines are also called bass-side machines. The treble strings are attached to the right three mechanics, which is why these mechanics are also called bass or treble side mechanics.
