so, it's the vca.....

That would be my guess. I seem to recall there may have been some resistor tweaking with the 110 for the first few months after they shipped (wasn't the 110 one of the first three modules to ship?). I'm pretty sure I have some resistors in parallel (soldered to the top of the other resistors) to accomplish some of this tweaking. I don't think I made all the changes that were mentioned since it was working very well and I was tired of working on it.

If yours is an early one, maybe you need to review to see if there are any updates which you missed. I'm pretty sure that mine doesn't line up with the 0 tick mark when the VCA goes to zero (I can't remember which way it's offset).

But I also had a problem with my 110. Since the CV MOD pot has wires flown to it but has no solder lugs, kit builders had to bend the pins around the wires and add heat shrink around them for protection. I didn't have a heat shrink gun at the time and tried to melt the heat shrink by getting the tip of the soldering iron VERY close to the heat shrink. I ended up cooking the pot but not realizing it for a while since it worked well in most positions, but in some positions it had very strange symptoms.

You might want to look into that too.
