Valve guards are used to protect the surface of the trumpet from the sweat and oils from the player’s hand. Also good for stopping the player’s hand going green if playing a raw brass trumpet. Trumpet valve guards are available in two styles, the type that is attached with a lace, this is a traditional style, & the type that is attached by velcro which is a more modern invention. The velcro style has the advantage that it can be removed for cleaning much more quickly than the lace up type. Velcro was originally envisioned as a fastener for clothing, today, Velcro is used across a wide array of industries and applications; including healthcare, the military, land vehicles, aircraft, and even trumpet valve guards.
