Mastermind Power adapter polarity

I was using a 7 pin cable from my RG-16 to power my Mastermind, but I found another use for the pedal with a device that won't power it. Unfortunately, I can't find the original power adapter so I'm looking for one. What polarity should the adapter be? Center negative or center positive? I just want to make sure I'm getting the right thing.
 
The Mastermind will take either polarity. 9VDC is the recommended voltage, although it will take 12VDC as well. (or 9VAC).
