Denis Wick Heavytop Conversion Booster for Medium Bore Trombone Mouthpieces
The Denis Wick Mouthpiece Booster is an attachment designed to be fitted to existing Denis Wick mouthpieces (and many other makes and models of mouthpieces). The Booster temporarily adds mass to the mouthpiece, enabling it to transfer more energy through the instrument, resulting in a more powerful sound and a more focused one.
