any oninions welcome
hi, im looking to build a graphic equaliser as a footswitch effect to go in between the mic and the mixer to use as a vocal effect,
anyone out there clued up on this kind of thing?
will probably use a basic electronics project from maplins or somewhere similar, any thoughts?
i thought this would be a good topic to discuss, as there are many people like myself who would like to know more about this kind of thing!!!!!!!!
yeah great reply, thanks for that, do you know much about this subject?????
Graphic EQ as a vocal effect?
I can't see many possibilities there mate.
For the effect that you're trying to achieve (I assume that it's going to be for telephone style vox), a graphic EQ would definitely be overkill.
its more of a megaphone sound im trying to achieve, but it needs to be bypassable mid performance by foot switch, i can achieve a near enough sound by dropping the bass and treble out of the vox mix, but its getting it into a foot switch is the problem,
what would you suggest as apposed to eq?

Well, it would be an EQ circuit, but definitely not a graphic EQ.
Now I haven't done electronic theory for a while, but I'm reckoning you could put a low-pass and high-pass filter together to create a band-pass, and that's like...4 or so components (two resistors, and two capacitors).
Passive filtering should be fine, but a pre-amp may be neccesary.
I might break out the soldering iron tomorrow and see if I can get a working design together...
Also, just found this interesting piece of software :)

It allows you to design a filter with the exact frequency response you're after, and it spits out a circuit diagram for you. Pretty fun to mess around with :D
nice one jarrydn,
nice to get a usefull and helpfull reply from someone, i think your spot on with the high/low pass filter,
will check out the link - that sound really cool, as i am new to electronics projects and that seems like exactly the kind of thing i'm after,
thanks again
If you're looking to get into electronics as a somewhat serious hobby, THIS is a good book to invest in. It will give you a solid overview of both AC and DC circuit analysis.
Regarding the effect, a bandpass is exactly what you're looking for.
Here's a site with some information about filters.
thanks people, very helpfull, will check out all the link asap.
cheers
