I am making the last batch of my super high quality Analog Four CV interfaces before Xmas, so if you would like to get one or 2 in time for Santa to get them in your stocking then let me know, trust me these are much better than fiddling around with messy adapters, and are built with high quality parts throughout. Make an ideal Xmas gift to yourself!
Postage is the same if you have one or 2 as they are the small parcel rate, if buying 2 you can use a sharpie to black out the A or C and B or D as appropriate.
