What is the difference between an open knob and a closed KNOB
The reason for the open knob is aesthetics,
It looks exquisite and is influenced by the aesthetics of punk period
The advantage is exquisite,
The disadvantage is that it is exposed to the air for a long time. If it is the open knob of the low-end piano, it is easy to rust, resulting in the failure of the knob and inaccurate tuning. It needs cleaning and cleaning to taste, which is more troublesome
The closed knob is that the gear is protected, with long service life, durability, easy to use and no need to clean.
However, closed knobs are recommended. Now tens of thousands of piano closed knobs are equipped with string lock, which is very exquisite, high-grade and convenient.
