I've heard that bass should always been told that bass should always remain mono for many reasons. That it prevents phasing, it creates an upfront feeling in a mix, anything other than mono is really bad for playing in a club because it's disorienting, that the human ear has trouble distinguishing the direction of low frequencies in an open environment (rather than through headphones), etc. Some of those I might of pulled out of my ass but I swear I think I've heard them somewhere.
Now I do hear plenty of stereo basses but I assumed the formula was this: You either have a totally mono bass or you have a 2 part bass, the sub bass and the bass. You keep the sub bass 100% mono (of course) and the bass you can give more stereo freedom. The higher the frequency the wider you can pan it. Pads, synths, high hats, and stuff like that are panned widely. Songs with widely panned low frequencies usually really bother me through headphones. To get an idea of what I'm talking about, I consider this song to have a standard stereo field and represent the above formula perfectly.
BUT! I've been listening to some of John O'Callaghan's stuff and I'm wondering, what the hell does he do with his bass?! It's huge! His songs are like 90% bass and it's VERY stereo. Sounds like it's completely surrounding you. In fact it seems to be lacking a bit in the middle and the kick fills up the space there. It's not just the higher bass either, it seems to be all of it, even the sub, is pushed off to the sides? Here listen to this song The way he mixes is like totally different from anyone else's. He doesn't follow the formula I wrote above. He does the opposite. In fact the higher frequencies are more or less pushed towards the CENTER. He's breaking like every rule I use to try to give my songs a good stereo field, but it sounds so freaking GOOD.
When you compare the two songs, it's obvious how very different the two mixes are! Like night and day! Which do you prefer?
So what is going on here?! How does he prevent phasing? I can't even prevent phasing with a 100% mono bass! How do I get the bass this huge? What am I doing wrong? What SHOULD you do with bass?
