The Denis Wick stretchable bell cover reduces the risk of spreading harmful airborne droplets and aerosols produced by brass instruments. The covers are very easy to fit and make no perceptible difference to the sound of the instrument. The player might notice a very slight difference in response in the high register, and the tone is only minimally affected.
Bell covers are available in the following sizes –
Tenor Horn/Trombone (8½”)
Baritone/Bass Trombone (9½”)
