Shape and size: Reeds can be customised in shape and size to suit different applications. For example, accordion reeds are one of the most important parts of the accordion, in the 1980s to 1990s, the Shanghai Baille Factory, Tianjin Parrot production of brand-name series of accordions using the top grade reeds, but today's price of 5,000 yuan up and down the accordion's reeds are shaped like haggis, easy to fracture, the replacemen…
