The sound of your instruments changed due to multiple variables. We considered how to best express the beautiful sound of instrument, and as a result, we developed an endpin with structural stability and amplification. 

The developer as an engineer is a composite material expert, and has done continuous researches for many years considering the material (carbon fiber, brass), stiffness, and the path of the sound, which affect the vibration characteristics of the sound. By working together with many experts in diverse fields, we have launched our Durod endpin.
