Change order of effects switch

I wanted to make a duel effect pedal that had a switch to change the order of the internal effects. So for an example a tremolo > fuzz and at a punch of a button it would be a fuzz > tremolo. The order of some effects will drastically change the characteristics of the sound. I found that Beavis Audio had a nice layout for this with the help of the people at I<3Fuzz and I did a quick layout for a PCB. This is what I came up with.

SA = Send A
IN = Input
SB = Send B
RA = Return A
O = Output
RB = Return B
LA = LED A
LB = LED B
