I am using an MVP expression pedal to control volume for Hammonsd SK1. I'm not sure that I have the proper hook up because the volume goes from soft to loud without any subtle variation. How should I cable this? Do I need an insert cable and if so how is this wired? Is there a wire diagram available? Thank you in advance for any information.

Are you using it like an expression pedal or a volume pedal?
The correct way to do it would be Hammond -> MVP In, then MVP Out -> Amp/PA system.

It's powered correctly (power supply or battery)?
And have you adjusted the pots? The gain pot sets a boost level- turn that fully counterclockwise. And the min pot sets the minimum level- again, set it counterclockwise.

Is it the 25k or 250k version? For active signals (your keyboard) you'll have a better taper with the 25k. If you have the 250k version, there should be a taper switch you can flip to help a bit.
Other than that ... there's no magic. It's a passive volume pedal, essentially a potentiometer with a foot pedal on top. If you have a multimeter, you could always measure the resistance from the input to output to test the sweep.

Glad you got that sorted out.
