3PDT Stomp Switch wiring for Stomp Shield?

How would I connect a stomp switch (3 pole double throw) to the pcb, to make the input signal bypass the filtering circuit and go to output?

this can be done using only 2 of the "poles" in the switch. most stompboxes use the third "pole" for turning on an LED to indicate the effect is on. basically, you connect the output 1/4" jack to one "pole", and the input 1/4" jack to another. then the "on" position for each switch is connected to the circuit's output/input, and the "off" positions are shorted together, so the signal just flows through them. there is a picture of it here:
