By adding mass to the entry and exit points on the valve section of your horn, the trumpet's optimal resistance can be obtained. The weight of the CCAPS in the proper position on the valve section can provide a denser, more centered sound, along with a more stable harmonic series. Overall response and attacks are more even throughout the range of the horn as well. Used alone or in conjunction with the supplied shims and O-rings you can find the best combination for you.
MAGNUM CCAPS are specifically designed for players that want the utmost in slotting and projection. At 1.75 oz. each they provide the slotting stability that lets you perform with confidence under the loudest conditions! Note: These are 1" in total length. Your horn may not fit into your standard hard case without removal. Consider a gig bag. (Magnum CCAPS are available in #1, #2, #3, #4 sizes only.)
