DIY one-string electric bass guitar made from PVC and wood

This Weekend Project for making a one-string, electric bass guitar from MAKE is a pretty sweet DIY for a parent and his teenager to tackle and bond over. Using PVC, wood and a few other guitar related components easily picked up from your local music store the finished guitar plays and sounds like a bass. You'll get your kid back for a weekend. Your kid will learn a little something about the science of sound and vibration, the workings and construction of an electric guitar and, perhaps, that you're not totally square.
