a/b box, tuner out, and buffer

[Rawkcraze]

im trying to make an a/b box for my friend because he wants to switch between acoustic/electric, amp/front of house, in one stomp. he also wants to use a tuner, but not have to buy 2 of them for each guitar.
my solution for this was an a/b box with 2 inputs and 2 outputs, a tuner out, and a built in GGG buffer. im just having a hard time wiring in Led's and figuring out if the buffer should go before or after the tuner out.
so far heres my layout:
3pdt:

123
456   (so 1-4, 2-5, 3-6 are connected in the up position)
789

1: In1
2:- of led1
3:Out1
4:buffer in
5: ground
6: buffer out and tuner out
7: In2
8:- of led2
9:Out2

is it a good idea to have the buffer out and tuner out put together? or should i put the tuner out before the buffer?
thanks
