So you run omnis for every show, then? Never use a HPF? In a way, running cards or hypers - and certainly running a high pass filter - is a way of "cleaning up" the recording - it just happens at the time the recording is made, instead of in post. I personally don't see a distinction between the two. Do you?
Omnis? Nope, I've got one set of mics due to budget reasons more then anything else.
HPF? Nope, never have.
I got into taping after listening to a lot of Zeppelin tapes, many of which people openly admited trying to EQ, and failing miserably. It left a mark on me, thats part of why I leave recordings as they are and have that philosophy. Experiences shape people, thats mine.
