"Cool Jazz" is a stemless version of the already released "Wah Wah & Cool Jazz." There are many people who do not use stems, and we have reduced the price by eliminating stems. (The stem is not sold separately.) By combining it with "Warm-up nano", it is no exaggeration to say that it is the strongest mute in terms of performance. Weight: Aluminum 55g, Copper 132g, Brass 123g
