Pearl changed the part number to from RDMM to PEMM in April 2018. Fits Mimic Pro and this is not included with Mimic Pro from Pearl so add this if you need a mount. Also works with some of the larger Roland modules like the TD-10, TD-20, TD-30, and TD-50. Fits into a normal sized multi-clamp. Comes with 2 types of mounting screws including some designed for Mimic Pro.
