Designed and made by Heavy Bottom Caps — a division of Ray Farr Flugels, the heavy bottom cap has been sold worldwide to befit players on all types of instruments.

A Heavy Bottom Cap replaces your 3rd valve bottom cap. It's 38mm long and the same diameter and thread as your instrument.

Helps

It helps in terms sound and projection, as the added mass attenuates the harmonic partials (the full spectrum of sound colour within each semi-tone).

Do they work? The evidence is yes, but just to make sure, you can try one for 1 month approval and see — anywhere in the world! If it's not for you, simply return and a full refund is given.

Other instruments makes and types are also available
