Autonomous Bassline Generator 

Builder's Guide 1.0.2

Step 1: Get comfortable

Look at the graphical parts list, compare the parts you have to the pictures and make sure you can 
identify every component. Look at the color bands on the resistors. Read the numbers on the other 
components.

It's also a good idea to spend a moment getting familiar with the PCB, too.

Pull out your tools: soldering iron, solder, flush cutters, maybe needle-nose pliers.

Take a deep breath.... here we go!
