FBV Shortboard MKII volume pedal question.

I’m using this new model pedal for my new Spider Valve 212 mp-1.  I used it live for the first time this past weekend and discovered the volume pedal is way too touchy.  I could like to have it be full volume pressed all the way up, and when backed off all the way only reduce the volume to 60%.      How would I make this adjustment?  And, can I make this adjustment?

Also, future question: I’m going to purchase the additional EX-1 expression pedal so I have a permanent wha pedal (which I’ll want configured to sound just like Man in a Box).  Are these configurable – and if so – same question as above, how?

Thanks
