Anyone recommend an effective, low-profile shock mount that would be suited for use of an ATM-450 on a H-clamp? At first I thought it was the speaker on the Mackie SRM150. But I recall that while I had to dial back the bass when using a pick-up, it did not appear to have what I'll describe as a kind of higher frequency rattling sound. When I took the mic and ran it into the Woods and my EA vl110- the rattling followed. It seemed to dissipate when squeezed/stabilized the mic (while on H-Clamp) with my hand.
