Well. I got the Memory toy too. I’m french. So… Do you really think that these trimpots are here because of the differences that may exist between BBDs? If that’s correct (I think it is), then do you really think that someone check every pedal made with a scope and a screwdriver to set all the trims to the correct value??? I think it unbelievable.
What I think is that the trimpots are pre-seted and soldered in the pedal. Then, if any customer have bad experince with its pedal, then he send it back to manufacturer, and then, a tech may set the trimpots.

So, What I think is the trimpots are factory setted to an average value, and they may be re-setted for ideal operation. So the pedal you buy may be very good or very bad, or anything in between, and most of the pedal are just average.

That’s only my opinion, and I’ll probably NOT TOUCH THE TRIMS because I really don’t know wich affects what… I find on the web that trim 1 could affect the feedback level, as when turned clockwise a bit, the deay may self oscilate. But again, I think the average setting is correct for me, even if the delay knob is not very effective and the feedback knob offer no more than 5 decreasing repeats.
