How to Replace Missing Reeds in a Hohner 280C Chromonica 64

简介

The Hohner 280C Chromonica 64 Chromatic Harmonica loses its plastic reeds over time as its binding glue degrades. This results in the harmonica not making sound where the reeds are missing. This guide will go through the steps needed to take off the face plates of the harmonica, replace the fallen reeds using glue, and reassemble the instrument.
