The Universal Shock Mount from ProAm USA is a dual-stage shock mount for microphones. It can be used to securely support any microphone with a diameter of 0.38" to 1.75". This shock mount fits standard microphone stands with a 5/8" thread.
With this shock mount, I can literally *pound* on my desk and absolutely no resonance gets through the arm into the mic. I'm using this for my Audio-Technica ATR 2100 (the old mini USB model, not the newer X model with USB type C) which is about 28 mm in diameter, and the bands across the front and back hold it very nicely even though the actual sleeve is made for a 52 mm microphone. The isolation is PHENOMENAL. My super cheap mic arm is attached to my desk and used to send a resonating gong type sound into the mic any time something impacted the desk (a drink, my hand, etc.) and I hated subjecting my stream audience to that. That's no longer a worry!
I tried 3 previous shock mounts claiming to be able to hold a 42mm mic. I might as well have been using scotch tape. None of them would grip enough to keep the mic from easily sliding through. I am using this on a vintage (heavy) AKG tube mic, so I needed something really secure. This unit has both a spring clamp, and the quadruple rubber band style you see on SDC mics. Great job. It is actually better than the factory unit. Finally got something that works!
