One thing I always have to remind myself about kick and bass is that both of these sources cover a gigantic amount of space in the entire frequency field. They are basically covering most of every frequency we hear in a mix. They are key to the energy in any mix. Therefore they require a considerable amount of attention when tracking IMO.
Concerning bass guitar...
I have an 8x10 cab that was built by a friend of mine loaded with these Eminance speakers with huge cones. It's the loudest 8x10 I think I have ever heard in my life - no matter what head you run through it, it's a beast.
Tracking bass, I almost always use an SM57 on the 8x10 through my Dan Alexander 1272 with a touch of Distressor - well, maybe more than a touch, but it sounds sooo good. Don't over-compress. Just smooth it out till it feels right with the other stuff going on in the song.
If I want more beef in the low end I will throw a D112, Beta52 or a comparible dynamic with a low-end emphasis on the bottom of the cab. Make sure it's in phase with the 57 or shift it around in your DAW later if you're lazy.
Between those two mics or the combination of the two, I always find the right amount of growl, low end and presence to make everyone happy. I've sent my tracks to other mixers who agree.
Any other methods to this madness??? I'm curious to know what some other techniques are. Thanks for listening.
