If you know how to solder and plug some components into a breadboard, you have all the skills you need to build your own homemade guitar amplifier. It doesn’t have to involve any tubes or dangerous voltage. In fact, the design in this project is powered by a simple 9-volt battery and built only with parts that you can pick up today at an electronics store.

The design is based on the “Little Gem” amplifier circuit from runoffgroove.com. There are a lot of other great guitar circuits there for you to explore once you get the hang of it!
