newbie question - one knob turns easier than all others

[intensemojo]

I just got my MB yesterday, registered and found the this forum. Awesome!

While using the MB last night  I noticed that the Env Amount knob in the square oscillator section moves much more freely than any other. It still clicks at 0 but is probable 50% easier than the others. I can still hear it working but was wondering if should be concerned or chalk it up as normal. Sorry for the newbie question.

It is normal - for some reason it uses a different pot than the others.
