Using two booms, two stands for two microphones on a single guitar cabinet can be tricky--they are difficult to get positioned exactly where you want them on only a single speaker.

Made from injected molded polymer plastic, the AxeMount has a threaded brass insert in its base so that the threads will not wear out as is the case with all--plastic mic clips. The AxeMount lines up the SM57's diaphragm with the "ears"--the magnets on the left and right sides of the side-address R-121's ribbon element.

There is a small arrow on the AxeMount near the Royer badge logo to line up to the "seam" surrounding the 57's body. This feature makes it a no brainer for fast and dependable setups and is consistent enough that it'll work well most of the time. Of course you can slide the 57 back and forth or in and out of the clip for different sounds but starting out with the alignment arrow is always a good idea.

The AxeMount SM-21 Dual Microphone Clip is essential for recording guitar cabinet speakers. Usually the Royer R-121 ribbon is aimed at the center of the dust cover, and the SM-57 offset towards the cone itself. I liked being able to move both microphones together in tandem when dialing in tone with just the right balance somewhere between the high frequencies with attack and edginess (dust cover) and warmth and thickness (towards the cone).

The AxeMount SM-21 Dual Microphone Mount sells for $49.99 and joins SLR's line of dual microphone clips and mounts such as the X-Clip and X Mount products.
