Here's one fresh off the printer. It's a little bulkier than the original, but I think it captures the nice, solid, chunky sound. I also really like the way the sound rolls off naturally once the rate gets high enough.

Takes a standard 9V, but a 15V battery would get a bit more oomph out of it.

I still owe you one of my SK-1 clones! They work great with the CDV-700s.
