[sdiy] Re: Famous Fixed Filters - FFF PCB ? Moog Parametric?

[Florian Anwander]

Hi,

I think the secret of the the moog parametric is, that it is able to 
achieve a very narrow bandwith without falling into full selfresonance.
You can create a Dub-TR808 Bassdrum with it from a simple Click, but the 
EQ never falls in full resonance. Btw: the parametric EQ of the polymoog 
is similar.
I have the schematics for the moog parametric at home; I will scan it 
the next days.

Of course, thats what all (fixed or not) filters do... ;-)

Thats not an ability of the EQ - its an ability (and a knowledge) of the 
user in front of the EQ ;-).
For my book I recorded an example with an Boss GE10 graphic EQ, where I 
create basic vocal sounds - the knowledge about where the frequencies 
for the vocals are located comes from a book: The example is spoken in 
german and also the sound of the vocals is related to how they are 
spoken in german, but I think, you will recognize it:
