i ran the 4v's for summer tour 99 and was less than satisfied with the results. at the time i was running into the old vms box. when i ran them i ran them both vertically and ortf. there is definitely a difference in the sound depending on which way you run them. i liked them more when i ran them ortf. i used the schoeps stc bar. to do this it looks like the mics are facing the back of the room. for my tastes, though, i just could not see me taping the majority of shows with them. i thought the bass was a little muddy and the highs were too brittle. kinda overexaggerated and electronic sounding to my ears.
now, having said that, i have heard MANY nice tapes bri and others have pulled with these mics. usually the tapes i like with them are in small venues up front. that is where i believe they tend to shine. anyway, i got the 41's after that tour and have never been happier. the highs on the 41's are so sweet!!!!! imo, it is the best all around cap schoeps makes.
have fun,
dave
