Mounting the RM1 RimMount to the Drum

The RM1 RimMount is designed for metal drum rims, and will not work on 

wooden drum rims. While reading this section, please refer to Figure 4-A, 

which refers to the various elements of the RimMount™. Mounting the Rim-

Mount to the drum rim is quite easy.  First, unscrew the thumbscrew so there 

is more than enough space for the Delrin® cushioned rim-guide to clear the 

bottom of the drum rim. Then determine where on the drum rim you want 

to place the microphone and place the top “hook portion” of the RimMount 

bracket over the drum rim. 

Figure 4-A.  Elements of the RM1 RimMount™

Referring  to  Figure  4-B,  notice  that  on  the  cushioned  rim-guide  there  are 

two sets of grooves. One set of grooves is in the “center” of the rim-guide, 

while the other set of grooves is “off center” (or closer to the edge of the 

rim-guide). These  two sets of grooves provide  you with “three” mounting 

options:  (1)  placing  the  “off  center”  rim-guide  grooves  close  to  the  drum 

shell, (2) or rotating the “off center” grooves 180 degrees will place the rim-

guide further away from the drum shell, and (3) 

the “center” grooves will allow placement in-be-

tween the positions described in 1 and 2.
