Not sure how common knowledge this little trick is, but damn is it handy. Did you know that you can change the "handedness" of a open gear style bass tuner?
Well, you can, and it's easy peasy. Super useful if you are doing a 3+1 headstock, you can only find a set of 4 in line when you need 2x2 or vice versa, or you need lefty and can only find righties!
Let's start with a right aligned tuner.
Unscrew the bolt and break it down to it's individual components.
Replace the post in the desired orientation.
