schematics.....

[John_C]

As part of a larger project i'm looking to build 2 graphic eq circuits for guitar

Does anyone have any schematics for guitar graphic EQ circuits?

The simpler the better as i'm not great at doing PCBs

thanks

Well here is the thing... Homemade 'graphic' eq's aren't that cheap. Well, it also depends on how many bands that you are looking for....

Why not just buy one?

But the BYOC kit is nice, if you are looking for a few bands.... You can just go off of their schematic and source it out yourself...

well this is what i'm looking at atm, i'll check out out the BYOC one as well

Hmm the only thing about that one is you need a bit of knowledge to find the proper IC to use with that, since it is obviously not listed.

I would just go with the BYOC, 10 bands and you can pick all the freqs based on what you want... Just buy the board from them, and buy all the components from small bear or mouser or whatever you guys use in the UK.... If I had to guess, I would say you could build one for <$50 USD

the thing is that they say they're not selling boards, possibly not for the whole of the year..................

hmmmmmmm

i do have access to etching equipment though so i could try making one

Shouldn't be too tough, since they give great accurate pictures of it
