Not sure if I posted this here already but another brand spankin new ds-1 arrived today. As know on the net as the keely mod. This 2 resistor swap with no led indicator will only put u in vintage mode which we all want anyway. I think the keely mod toggles between new and vintage not sure but why else for an extra led.
You'll now if your DS-1 is non vintage if it says made in Taiwan on the back. I believe that's when the minor design transistion took place in between the made in Taiwan to made in Japan phase.
