Modify FreakZEQ parametric for bass?

[theehman]

Bought the PCB and built it but I was hoping to use it on bass and it just doesn't work that well in the bass range.  I was wondering if someone with a better knowledge of filters could point out what to change to make it more bass friendly.  Schematic attached.

I suppose you could first try different cap values for

C8
C9
C10
C11

Do you have a Bass EQ pedal ? If yes, what are your favorite settings ?

I don't have an eq pedal at the moment

I dont have any experience in the requirements to EQ a bass sucessfully

besides the general notion that most important frequencies are much lower than those of a guitar

I can suggest normal idea of changing those caps that determine frequency, to lower them.

But maybe Bass has more requirements than just change the frequencies. For example, Bass might need more control bands.

But tell me, when you start to move your knobs in the direction that gives you better sound, in which direction do you turn the knobs ? You want even higher Q or even lower Q ?


The user manual does say :  The frequency selection is infinitely variable from almost sub-bass frequencies to high frequency definition and edge. The selected frequency band can be as wide as 2 octaves or as narrow as a single note.

If that is true, I wonder what needs to be tweaked.
