Is EQ something that should only be adjusted after recording vocals? I've read that compression can be applied before recording, but only if you know what you are doing since it can't be taken out. Is it the same deal with EQ? It sounds like some people cut or boost certain frequencies before the recording with good results so I was just wondering if I should try it or stick with safely applying after. If I should which frequencies are 'safer' or more typical to cut and boost without overdoing it? Thanks.
