Royer Labs AxeMount Dual-Microphone Clip

The SM-21 AxeMount Dual-Microphone Clip for R-121 and 57-Styled Dynamic Mics from Royer Labs is a microphone combo clip for mounting an R-121 ribbon mic and a 57-style dynamic microphone (sold separately) for capturing the audio of an electric-guitar cabinet. It can be used to position both mics simultaneously in a phase-aligned position—ready to record. In the past, using these two mics required two mic stands and two clips. With the SM-21 setup, a good starting point is positioning the clip, so the dynamic mic is pointed where the speaker dome meets the paper. The R-121 will be more on the dome of the speaker. This is the classic position for these two mics.
