Hey, thank you. I'm glad you like it. The materials I used to make the amp consists of PVC piping, rubber o-rings, sheets of pvc for the conductors, paint, electrical tape, and copper wire.. it was pretty easy to make really, it all comes down to tools. if you already have tools available you're good to go. When I made this I thought about the design long and hard and put it all together within 24 hours' time. So there you have it, i hope your project will come along nicely. Enjoy
