Some more fun with filters today. Today you get to hear what a Notch filter
sounds like, and how to use one. But first, some more filter basics:
Controls you get with Axe Filters –
Type – reviewed in last post.
Frequency – Sets the center freq of the filter
Order – choice of two different filter slopes (4th order has a more nasal, focused sound)
Q – the relative sharpness or broadness of the filter peak/notch (higher setting = sharper peak)
Gain – The amount of gain at the filter’s center frequency (how big the peak/notch is)
Level – Volume pot
Bal – Set to 0% for stereo, 100% or -100% for hard panned mono
Pan L,R – default is 100%/-100% stereo. Reset both to 0% for mono operation
Today we have a patch with the seldom used (in guitar applications) “notch” filter.
As we reviewed last time, a notch filter cuts a divot out of the frequencies.
If you attach an LFO or other controller to the frequency parameter of a Filter
Block, this filter makes a moving sweep out of the patch’s sound. What does that
sound like? Like the patch below. Very earthy, dark, and jazzy in
this case, because I programmed the sweep in the mid level frequencies.
Try some slow, jazz-y sounding chord progressions with this patch and see how you like it.
