all business during shows unless I'm doing patch-outs from a soundboard and things are running fine. Not a mic-stand taper myself (generally specialize in the wireless taping field) but would certainly do it if that yielded the best result at a particular show.
Sorry--misread your previous posts. Erroneously equated "taped with four decks" to "taped with four Tascam 2D internals". So you just place the decks and specific places around the venue and then pick up later, and then listen to the general best one?
I've gotten to placing the internals decks right onstage with low gain (levels between 88 and 92), which produces a pretty interesting sound (Kevn Kinney in '13 in Atlanta was like that, two decks on stage, then two more in the back of the room, one used with Sonics, the internals were very instrument heavy, whereas the back of the room had a pretty well-balanced sound). always wanted to try and run a matrix with those, possibly 4 channel, but figure that's something for my 60's....
have taped the Sonics to a balcony railing, to a back wall, to the vidcam tripod on a stick....every new venue creates a new set of challenges (for the video, vibration and rock shows is a huge issue)
