Thanks Greg,
I've experimented with ground effect quite a bit over the last year.
To my ear, the "fuller sound" you mention seems to become quite
noticeable at about 15" or so and increases rapidly to the point of
serious ugliness at ground level. But in the 18" to 24" range, there
seems to be a certain sweet clarity that seems to drop off ever so
slightly as the mic moves upward to about head height -- at least
that's what I've ovserved.
I've never done any serious experiments with higher elevations like
Walt and Dave have done. Hmmm... yup, that's definitely another
element to look into.
