I wanted a stand for my bass guitar, and I didn't want to shell out the $15 or so for a "real" one, so I decided to build my own. I was inspired by the PVC multiple guitar stand
and the Hole Shot
by Basturd Brother's Guitar Stands. I spent less than $5 on this project, but that's only because I get a sizable discount at the hardware store where my mom works. I can't imagine it'll cost more than $10.
