This pedalboard does what is described in this post: https://forum.moddevices.com/t/eq-but-the-boost-cut-frequencies-are-different/6313 It emulates TC Electronics BH550 Bass Amp EQ section, whereby the cut and boost frequencies are shifted. It only uses 4 filters (high- and low-pass are disabled), but the same principle can be used with those as well. A more thorough description is in the original post.
