Trumpet MODULE Bottom Valve Caps. KGUmusic


KGUmusic MODULE Bottom Valve Caps is a set of 5 independent parts that can be mixed in different combinations to achieve a desirable effect. Specially designed to emphasize the sound characteristics of every trumpet. It changes the resonance of the instrument through the addition of extra weight to the block of the bottom valve, making brass more stretchy which improves the instrument's tone, sound shades, response, and general feelings. Also, MODULE allows you to re-balance trumpet weight depending on which valve is equipped with it (especially if you additionally equip your trumpet with the Heavy mouthpiece or Booster).

 Another advantage of this upgrade is a tighter and more comfortable grip, which also brings positive changes to your playing.
