New Builder interested in building 6 band EQ Pedal

[blopper]

I don't care if it's pots or sliders/faders
I am competent at soldering, but am still new at learning circuits and what the various parts are and do.

not seeking hand-holding here, just a few basic pointers on where to start, where to get parts and housing etc.

Thanks!

Hi, welcome Blopper!

EQs can be pretty difficult to come up with, esp. as a first or new project.   If you want to learn more about them and how they are 'composed', there is some good info on this site:  https://sound-au.com/articles/gyrator-filters.htm   

All of it is germane to the topic, but if you skip down he sets up an EQ using the gyrators and discusses its operation.   Not sure about sourcing sliders if you want the classic EQ deal, I'm sure someone will come along with a seller shortly.   

I put the EQ in the category of something I'd buy (and have) rather than build, simply because it takes a lot to lay out and build.  I'd consider using gyrators for bass, mid and treble on a build tho, with lower Q's.

Are you looking at PCBs or kits?

The most expedient route is to get yourself a KA2223 or BA3812L.  These are inexpensive 16-in ICs, explicitly designed to simplify production of 5-band EQs.  Their datasheets illustrate how to add components on to the chip to make boost/cut of your specific needs.  I made one for myself, tailored to shape the mids, with the highest and lowest bands being 900 and something, down to 250hz or so.  I figured amp and guitar controls could take care of the rest.  But one can use the formulae provided to create whatever ranges one wishes.

Pedal PCB have a PCB, and you can also buy a faceplate so you don't have to try and cut the slits in your box https://www.pedalpcb.com/product/6-band-eq/
They also do the same circuit but with rotary pots - https://www.pedalpcb.com/product/pcb369/

These would be a pretty easy way to go if you don't want to do the design work yourself

What Mark said..
(it works for me with no issue..)

[Mark Hammer]

THAT's really interesting.  Thanks!

Welcome to the group !

A) do you mean GEQ or PEQ ?

B) The Guru RG Keen mentioned somewhere that the space taken by a dedicated GEQ chip and a discrete solution is about the same.

C) Noise can be an important consideration.

And clipping too!

D) There are many GEQ and PEQ kits available. Easy to search on the internet
