KGUMusic Yamaha Trim kit Heavy raw

Wow! This kit is absolutely fantastic - it changes completelly any trumpet, specially lightweight ones, or any trumpet you feel it doesn't have a very good slotting, or if you want more core to the sound. You can add only the bottom caps, or the entire kit, depending on your taste. For me it's what I wanted, for others may not be, so don't buy it if you don't need it !
