Tuning Your Guitar Should Be Easy
The knobs rotate in the plane that is perpendicular to the poster surface, but the pegheads rotate in t he plane that is parallel with the poster surfece. And there’s no clear feedforward of how the peghead rotate when you turn the knob.
The current tuning system is designed for precision tuning only, which means you have to rotate the knob a lot of times when you s to replace the strings.
The head of the guitar is the most vulnerable part, and the knobs are easily to be tuned accidentally.
