Want to build my own KMA Tyler clone, Pinball for filters?

Just as the subject says. If you're not familiar with the Tyler, here it is.

Basically a signal splitter into 2 loops enclosing a hi-pass filter on one and a lo-pass filter on the other.  I would plan to use this on my bass. Hard compression on the lo-pass side, and fuzz + mod on the hi-Pass side.

2 big unknowns for me are:
1. I don't know what a signal splitter looks like or if there is a DIY project out there I could use.
2. Would the pinball be a good option for the filters? I would need 2.  A tilt EQ is just a bit more functionality than I need, as each side would only need roll in one direction, not both, so I'm wondering if it's a disadvantage to use them this way or if I should keep looking for more simple Hi and Lo pass circuits.

Thoughts?
