Behringer BEQ700

I was considering the BEQ700 bass EQ pedal and noticed an interesting spread of frequencies; not your normal progression. 50 Hz, 120, 400, 500, 800, 4.5k and 10k. I took a look at component values. Using a simple (non-Spice) calculation:
Of course, component tolerances will affect this but it's curious that the "120Hz" filter should be that far out and that they have both 400 Hz and 500Hz sentre frequencies. It would be interesting to see the curves.
