3 band EQ...need a good shematic.

rockgardenlove · April 07, 2006, 03:45:40 AM

So I said that I would make a 3 band EQ pedal for this dude I know...only issue is, I can't find any good ones at all. Does anyone here know of a circuit with a treble band, mids band, and bass band? I'd like to hear a distinctive boost to certain frequencies, not just the standard bleed off technique...

Anyone have any suggestions?

Thanks for the link, but I've already tried a Fender style tone stack, wasn't really what I was looking for...I want something really defined with a definate frequency boost.

I also looked at this one:

How does that look? What might some suggested opamps be? I was thinking of just a TL072 or so...JRC4885?

Or one of those...which do you think would be better for my needs?

I'd grab your self a breadboard and throw some of these together and try them out yourself!

Try a TL074 or TL084 quad op-amp. You'll only need one chip then instead of two.

Might work better if those three sections were in parallel.
