All Brass Soundreturn for Trumpet bell
All Brass Soundreturn for Trumpet bell; a light-weight concave aluminum ring with three springs that grab onto the edge of the trumpet bell; very fitting for playing in loud environments when it is hard to hear one-self; better than sound reflectors, because it provides a much superior natural return due to its concave shape while also being free to move around; the size allows being used with wireless microphones and all kinds of mutes, even at the same time; Made in Argentina
