Start by checking the kind of pickups used with guitars. That will give an indication of the signals they output and the power needed to run them. Those are two key features of the amplifier design.

Without much money, I wanted to play an electric guitar. What I did is borrowed an old record player and took out the stylis. Then I tapped it to the top of my acoustic guitar and attatched longer wires back to the record player amp. The vibration of sound from the guitar traveled back through the stylis to the amp and it worked. However, there was a lot of feed back if I turned it up, which I did... it worked!

Hey, in Make magazine, this month there was an article on making an amp out of a cereal box. it really works and is very basic. If you want instructions on how to make a simple one, try that.

Power supply might be a good place tostart: it could determine whether you need power conditioning or not.
You may wish to consider impedance of the source (guitar) and output (speakers?) and decide what technologies to use
(vacuum tubes?, discrete transistors?, ICs?). These days, digital may be a consideration, since it could allow lots of filtering algorithms.

The Make magazine article is cute, might be worth a look: http://makezine.com/09/crackerboxamp/ (you'll need to click the "Download Sample PDF of this article (excerpt)." link)

That's a decent start, anyway.
