The rim is only half of the equation! Dial in the sound and support you are looking for with one of our three cup depths:
- D: Our deepest cup in our stock options, providing a very free-blowing experience. The extra depth allows for a warmer and richer tone color in the low register, without sacrificing the upper register.
- M: Our medium cup is the most popular model. It is a middle of the road cup designed to appeal to a broad range of performance genres.
- S: Our shallow cup provides more support in the middle and upper registers, adding some extra brilliance and efficiency.
