passive signal router

plug in 3 pedals and switch between signal routes 

A-->B-->C  
A-->C-->B  
B-->A-->C  
B-->C-->A  
C-->A-->B 
C-->B-->A

or A, B & C in parallel 

Its totally passive, the double sided PCB is sexy and the only component (other than the jack sockets) is that big switch bank

would a euro rack one of these be useful?
