Haha i actually am taking the main recording class this semester. I think the teacher just got off on a tangent. and idk why i said feel like. I know it's 7 bands
What I've read about the octave thing is, it's good for smoothing things out. For example, sometimes when mixing bass, you'll hear some notes louder than others. Obviously you'll use compression to sort that out to some degree, but EQing at different places will help even it out a little too. Before anyone flames me, this is what I've heard. I don't know how true it is, but I do think it makes sense
Something that help'd me was to put the kick mic about 6" aimed away from it just by a few degrees and it gets a good combo of click and boom. On Snare, I use a 57 and have it aimed at the center of the Snare. Of course, EQ and compression do wonders as well.
Seems like the first port of call everyone is heading towards is mics and placement... A better kick drum mic might help, but it sounds to me like you need some better drums and/or a better drummer.
Are they tuned right?
Is the player hitting them well (I don't mean hard)?
I've recorded drummers (such as Seb Rochford and Tony Allen) with 3 mics and everything has been perfectly balance and sounding right. Because the kit is set up properly and they hit them properly. Don't under estimate how important a good drummer and kit is. mixtipsblog.blogspot.com/2011/08/in-beginning-instruments.html
