While the server was being swapped, I was over on the MIMF going through the archives and came across these plans for a bass PVC bass flute. It's really only a bass by name, certainly not in register but I thought that with all of the octave shifters and other effects at our disposal, it would be something to wire a piezo into one of these and have at it. Maybe do something in loop with it.
