Notch/Low Cut Filters

[Daniel Yeabsley]

Here's my (uneducated) answer: The notch filter 'slices out' a narrow section of your sound. It can be useful for removing feedback or resonance at specific points in the audio spectrum.

The low-cut filter, on the other hand, removes everything below a certain frequency. Very useful for clearing up a muddy sounding room, or taking away 'rumbles' if you're using a microphone.

I just wish my iAmp came with a low-cut filter!
