This depends on a variety of factors, such as how often and hard you play. You should consider changing your drumheads if you notice two visual conditions called dips and dents. These conditions will affect the feel and response of the drumhead, along with a loss of energy transfer to the drum shell. If you are playing live shows (2-4 times a month) and rehearsing (1-3 times per week), we recommend changing your drumheads once every two months. We recommend changing your drumheads every six months for recreational playing at home, in a practice room, or just having fun.
