Gasp! An electric guitar, but no amp, and no money! What to do!
Fear not, my dad was a HAM enthusiast. He had a "Mono" 9V-powered mixer and some old headphones lying around. Paired together, they offered some decent amplification to the guitar sound. As @hikari mentioned, just plug the damn thing into a damn amplifier, and you have interesting sound.
A happy accident is that the amplifier in this "mono" thing was pretty crappy, so turning the knob to 6 and above resulted in a neat "distortion" effect.
And that's, folks, how I've been playing my electric guitar for the next 4 years, until I saved for an amp!
And with this setup, I finally composed my very first "song", and tried to start my first band.
