The BERP COVID kit has brought an awareness to brass players- not just about projecting airborne virus from their instruments (especially if they’ve been using their BERP to enhance their air speed/production), but also about condensation containment.

The Berp Covid cover on my baritone/euphonium is actually no problem at all. Truly! My horn still plays great and the magical Berp bell cover reduces the possible spread of germs.

The COVID issue has curtailed many musicians for fear of airborne contagion. The Berp Covid Kit has provided me a simple and sure way to appropriately cover the bell in a pleasant and practical manner while playing music in public.
