Definition: Feedback is among the most annoying things to happen in live sound; however, it can also be beneficial in studio situations.
Feedback occurs when certain frequency ranges are re-amplified from an amplifier through the device's pickup, be it a microphone or instrument amp.
Killing feedback in a live sound situation is always a battle, especially with vocal microphones and on-stage monitors. Reducing certain frequencies in master EQ settings almost always is necessary (especially around 1kHz). In a studio situation, feedback can help give an interesting (and sometimes desirable) tone to a guitar sound.
