Thanks Walt, I did mean to de-couple it, so as to observe the
difference between the SASS and the PB Ring, while still having some
way to hold up the mics on my tripod stand. Someone, can't find out
who it was, said in the thread that the SASS works the same as the PB
Ring, and you confirm that, as do my results.
And thanks again for the mod SASS--it is my main gear for soundscape
work, which is mostly what I am doing now, recording as many as I can
in Hawaii. I spend a lot of time just listening with it.
Your caution taken re: the screw.
Aloha,
David
