what am i looking for?

[kepeb]

taking a break from messing with my amps while they still work
i can try to describe but i dont know what it is i'm looking for...

my goal is to have my ideal mix of two circuits in a guitar chain taking only one spot.
i have two fuzz's, i want the signal split and sent to both.

then output high end from one and the low end from the other. i intend to incorporate this into one box to simplify when its completed.

i would like the hi/lo choice switchable so i can use either filter on either channel and then have them summed back to a single mono signal before the output.

so upto now i have a messy cut/paste idea which involves all the original controls for each pedal and additional mix pot controlling level out from each and the crossover frequency but with one 3pdt footswitch.

i have my diagrams for highpass/lowpass filters and an idea of an opamp summing circuit i could use but i am unsure of in and out impedences, the initial signal splitting, and any grounding/noise issues i may run into with this approach of them all in the sam box or sharing power.

any thoughts? or maybe you could point me to a similar thread somewhere
thanks guys

The first thing that comes to mind is Craig Anderton's PAIA Quadrafuzz circuit.

He split the signal into 4 frequency bands. While it is not quite the same as what you propose, look at his design and see if there is anything that makes your life easier.
