KGUBrass MONSTRO Bottom Valve Cap is specially designed to emphasize sound characteristics of every trumpet. It changes the resonance of the instrument through the addition of extra weight to one valve, makes brass more stretchy, which improves instrument's tone, sound shades, response and general feelings. Also MONSTRO allows to re-balance a trumpet depending on which valve is equipped with it. Another advantage of this upgrade is a tighter and more comfortable grip, which also brings positive changes to your playing.
