Jeri shares some interesting build details of the C64 Bass Guitar. The brains of the system is a Spartan FPGA, I was surprized to see that the pickups were made using round disk piezo elements that were cut into rectangles. I didn’t think that a piezo element would work properly if it were cut like that. I guess they are much more robust that I had thought! If you think the sound reminds you of the original C-64 sound you are correct, the sound chip used in the project is the famous SID 6581 that was used in the C-64.
