Location: Capital District, NY, USA Minor Outlying Islands | I was wondering ... why call a notch filter, a notch filter? Why not call it a feedback filter? I know there's probably a simple answer. |

Location: Scotland | the "feedback filter" produces a very steep reduction in output(-32dB) at a specific user-defined frequency, and this cut has a very narrow bandwidth. If the guitar's frequency response was plotted as a graph with the filter on, it would literally look as if someone had taken a very sharp axe and chopped a "notch" into the response curve. |

Do they have automatic multi notch feedback filters available yet?
I'm asking cuz I got to play with a real nice heterodyne filter that will do multiple tones so fast that it seems as if its simultanious (radio gear).
My instant thought was this would be WAY cool for live stage use. |

Location: Scotland | several companies including Sabine and Behringer make multi-notch automatic feedback destroyers. I have a Behringer Shark in my acoustic rig, very effective & very inexpensive

Why notch? When you can feedback filter!
