Hi everyone,
I've got plans to build my own EQ, and I've been looking around at pre-drawn schematics, but being no electrical engineer, I've got a whole myriad of small questions.
First, I should explain what I'm hoping to achieve:
Here is one of the schematics I've been looking at.
To the best of my knowledge, those op-amps will do just fine, but that opinion is biased towards the fact that I wouldn't know what to do with the circuit to use different ones.
For the questions though, these are mostly small, but I would really appreciate any help determining the following:
Of course, I can give more details upon request, but that's the basics of it I think.
Thanks!

Here's a page with some other EQ designs, parametric and graphic using gyrators, you might want to have a look at those.

As for opamp type, you'll probably not want to use 741's. There would be little if any change in the circuit when using other opamps. 5534's would probably be a good choice.
To make 2 channels you'd simply duplicate the equalizer part, and use one power supply to power both.
