Fighting Feedback

1.Start with the Phase switch in the left position and the Depth control at 5:00.

2.Turn your amp or PA up so that it is on the verge of feedback.

3.Flip the Phase switch back and forth until you find the position that sounds good and doesn’t feed back from open G and above (mid-bass feedback).

4.Turn up the amp some more until you get feedback around open D and below (deep-bass feedback).

5.Move the Depth control counter-clockwise until deep bass feedback goes away. (usually between 9:00 and 10:00).
