Maybe a Fuzz

00:36:32

Copied this out of a transistor circuits book but all I get when I breadboard is a very quiet guitar and it still sounds clean. I must be making a mistake somewhere, any thoughts?

It needs some refining. I'll give you an example

I wish I understood how each component affects the signal along the way. Kind of like a timeline of the signal and which to tweak to get a desired effect

Looks like it is working. Sine wave top and bottom is flatted out output. Chords sound different, right?

So far when I've breadboarded this the resulting signal is very sputtery as if my guitar isn't outputting enough signal to keep the transistors open but only for a quick pop. Also when I took the diodes out the sound didn't change at all so perhaps I have them wired in wrong... I wish I could see the angry pixies moving through the wires in real life :)

That's because the input level is low. Also quitar pickups have a high output impedance. Try using an op amp. It has high input impedance, low output impedance and you can introduce the diode limiting directly at the negative feedback.

A normal E Guitar has a peak output of ~100mV. And that is perfect for feeding an oldschool Fuzzbox, no OpAmp needed. Just check your breadbord thoroughly..
