<div>It took me awhile to get to this entry but here we go. Phase. What is it and why should we care about it? Well, phase issues appear from time to time and will (most often) have a negative impact on your recordings. Recordings that are out of phase will sound thin, muddy and just generally not too good. Phase issues can be difficult to track down. Microphones should be positioned in such a way as to reduce the possibility of phase issues.
An interesting psychoacoustic phenomenom occurs regarding phase. If you flip phase on one of two identical tracks they will cancel each other out.</div>

Ya, it has its place on both sides of the fence. Guitar pickups are a good example of using out of phase to your advantage. I think that in the studio it has to be look at as a negative *for the most part*
