A/B is the most simple stereo technique to use. Quite simply, two microphones are pointed straight ahead at a source. This technique sounds surprisingly good on acoustic guitar and very close to the front while recording live; however, there's not much stereo image, if any, and a lot of ambient information is lost.
A/B is the preferred method of tapers who stack tape - taping close to the speakers to get a cleaner sound. However, A/B isn't as useful for taping further back, as a good stereo image is necessary for full reproduction of the event.
