Hi Worshipbass, I don't check in here much but happened to see this post. I assume you're talking about the Boost-EQ? The MIDS control on that pedal is centered at 900Hz and provides either boost or cut. When centered (indicator line at noon) it's flat, turning it up boosts 900Hz, turning it down cuts 900Hz.
I hope that's helpful!
