Durod started with "Sympathy for Sound."

All instruments can't be expensive instruments, but I believe that they can be good instruments, We developed cello endpins by comparing various materials. Durod is a product that combines the advantages of Carbon and Brass. Unlike conventional carbon pipes in Durod, Spike has brass inside. It improves the vibration volume and vibration persistence of the instrument. In other words, the instrument sounds louder and softer and more concentrated.
