Hi Klas,
Bravo!
i love the bassy flutterings and this rig captures it amazingly .... correc=
t me if i am wrong , but it seems that thunderstorms and wind sounds would =
be appropriate for this set up.The environmental ambient is more my interes=
t in nature recording,, so sometimes talk of titmouse bore me as much as th=
e gear talk does for the titmouse folks.... get that price worked up so tho=
se preorders can start stacking up on your desk.
