I am currently working on an audio project for guitar i'm working on.
the frequency i will be working with is between 30Hz and 10KHz approximately. the supply i will be working with is +9v and Ground provided by an AC adaptor.
I would prfer to use single ICs to Transistors. The circuit will buffer an ac input then split the signal in 5, then re-buffer all 5 outputs.
It would greatly help if someone could provide a circuit diagram as well as any formulas or calculations i can use to modify the circuit for some gain.

thanks in advanced.

Edit: i found a circuit in my teacher's notes, but I couldn't find the formulas he used to calculate it. (view attached PDF)
