For trumpet & horn
A limited edition of the first Berp design and called the “Classic” was made for some hard core fans who have been asking for the original for many years.
The Classic functions very well when you cannot have your instrument to “berp” on, and you are satisfied with the resistance it provides. It looks great, and some say gets a better buzz sound than the present design. If you are a trumpet or horn player I suggest you buy one of each and never leave home without your Berp.
