A bit of a complex question but i'm really getting into electronics. I've been doing a lot in my a level physics class and i have had an idea.

I want to be able to produce synthesizing effect pedals, stuff like you would hear coming from a proper analogue synthesizer keyboard only, from a guitar.

I'd like to build some sort of frequency oscillator and square wave filter to have a play around with.

Is this something that can be done? if so are there any articles/books you recommend i read before i start?

oh and, i've been shown a circuit similar to the one show below. I was wondering what would happen if i ran a guitar signal through that? would it produce anything interesting?
