Reeves 43W Rim – Inner Diameter = .671″ (17.04 mm)
Our R3W ESVR has a rim similar to a Reeves 43W with our ESVR cup. It's a great lead mouthpiece for players who like a 3C-ish diameter with more cushion on the rim.

Players coming from a Reeves 43W/ES or equivalent report our Flex R3W ESVR is 10-30% easier to play with better intonation and a more resonant sound.
This is due to our advanced acoustic design and Flex Alloy.
