Convenient for those who have an Erhu with wooden tuning pegs. Attach one to the outer string and one to the inner string. Even if you can tune the instrument to some extent, it's difficult to fine-tune the sound. Using these adjusters allows for fine tuning. By turning the adjuster screws, the strings will subtly loosen or tighten, allowing you to adjust the pitch♪ ⚫︎I also use these adjusters, and I recommend them⚫︎ *Since these are imported goods, please refrain from purchasing if you are looking for a perfect product.
