I have a (or more probably several) recording opportunities coming up at a small place. I will have the possiblity to do soundboard and four mics. Two of them are cards and the other two SP C4's (having both omnis and cards). I have recorded at this place before and the soundboard feed is usually not too good, both in terms of instruments not being present (I can solve this with direct outs->behringer mixer) and the sound tech not being the best and loving to touch everything throughout the sets. I can, if I want to, record six channels at once. The C4's are a new addition to the arsenal and I'm thinking about putting them onstage, and I've been reading up on the M/S technique (never tried it). Would this be a good choice? Would I use one omni and one card capsule? I should add I guess that this is a rock club. Any input appreciated.
