Mark Smart and Wayne Joness RULE!! DId you check out Wayne's description of how the GR-300 works? Good if you're into that sort of stuff.

I second that Mark Smart and Wayne Joness are the kings of GR300. I've had mine for over 20 years now and I've learned more about them in the last three years from their sites than I ever have. Wayne sells some very cool boxes as well.
