This scheme above is for Roland gear from the company's inception (1972), to the point where the numbers recycle in Nov '80, and then on for a second go through the 80s.The trick with BOSS pedals is that at the time of this serial scheme's turnaround, they were only using a basic 4-digit version of these numbers - 9400 for May 1980, 7800 for January 1979, and then 0500 for April 1981.These continued well past the "37" shown at the end of this table and continued through to the late 80s.So the date of my pedal would be around 1988,89 as there are no letters befor the number.So I guess my SD1 was MIT December 1980, which doesnt kind of make sense to me because I thought that MIT production didnt start til much later..I would of thought it would be in the late 80s or early 90s!That's based on the comment you just made about the letters been added around 1989!And also they did not start Manufacturing in Taiwan until around 1988!

77 until around May 1981 when they moved to paper labels with a full 6-digit number.

It is possible that others may exist, probably closer to 118k than 200k.

Between serial number 200k (1983) and 1600k (1996), the correlation is sequential but nonlinear as production increased or slowed down.

One of the outliers is a FX15 Swell Pedal at serial number 408k.

As the FX15 was a slow seller, it is reasonable to assume that many circuit boards were assembled but not immediately housed in an enclosure, which would explain why the component date was about two years younger than its serial number.
