We're examining waves and sound in physics, and our project is to build an instrument then explain how the different noises are being made. Considering I've been thinking about making my own bass recently, I thought this would be the perfect opportunity to go through with it. So I'm looking for suggestions on how I can make an easy, cheap build with a decent tone that I could still play in the future. Also any design ideas that would work here, something I was thinking of was making an acoustic bass instead of electric, how would that work out? Easier, harder? I'm looking for as much info as possible.
