when you design a graphic equalizer, you just need a sample circuit of a bandpass filter which you can find in any electronic books. you will find there the needed materials and the values for your materials(e.g. resistors-100 ohms). if you want a 3-band graphic equalizer(which i did), connect three bandpass filters and a summing amplifier to sum them up. if you want to check if your circuit works, download from the internet the program 'circuitmaker'. i forgot(sorry!) the site from where i downloaded it but you can search it on the net.
good luck on your project! i hope this will help you.
