Huge differences between EQ Filters?

[osum]

Hi there,

I was trying some different EQ plugins and I was wondering that the result of LPF/HPF very much differs from EQ to EQ. Look here: (of course you can hear it but as it's very good to see on a freqanalyze I made pictures)

This is a distorted rhythm guitar without LPF:

Using the Cubase Stock Channel EQ:

Waves Q1:

SSL X-EQ:

Why do all except the Cubase Channel EQ let so much fizz above the filter frequency pass? Ok the SSL X-EQ is the only one where you can set the db/octave but regardless that every setting (on the picture 6db/oct) let much more fizz thru than the Cubase one.

Am I crazy, drunk or what am I thinking wrong?

It looks to me like the only major difference is that the Cubase EQ is overall a few db's quieter than the other two.

EDIT: The meter on the right definitely supports that. There's a difference of about 3 db's.

I've been wondering this myself. Been thinking about copy/pasting the same EQ setting with different EQ plugins and seeing if it makes a difference. Haven't got around to it though

Most likely the main difference is in the curve. But just stating the obvious: use the setting that sounds best regardless what the reading is or how the curve looks..
