The Phazer is an analogue phase correction device designed to time-align two signals so that the fundamental frequency of both signals play at the same time. For instance, you may have one microphone on the batter-head of a kick drum for more attack while a second mic may be on the outside the drum to add body. When the kick-pedal strikes the batter-head, the sound of the first head will occur slightly before the second. Delaying the sound of the fi rst head so that both play at precisely the same moment will produce a fatter, richer tone. This same approach is particularly effective with guitar amplifi ers when combining a direct feed from a guitar amp with a microphone on the cabinet or when combining two room mics such as a close mic on an acoustic guitar and a second mic to pick up the room ambiance.
