I purchased the SC2.2 back when it debuted on the market somewhere around ’97 or so. The serial # is 100007. I was just curious to find out if my unit differs from the SC2.2 that were subsequently shipped. The plate on the back states the unit is an “SC2 v3.” Most of the SC2.2 units I see on ebay, etc. say “sc2.2 v3” on the back. I assume there are no sonic differences, but I thought it was interesting that it said SC2 on the back.
At that time there were a number of changes to the printed circuit layout…. This was because we were making a lot of them and kept improving the layout for purely manufacturing reasons…. the circuit and the sound of all the SC2 variants is the same. On the later ones I widened the choice of attack and release times, but they are basically the same.
