Aby box question

[Antonio1963]

I am building this  ABY box
http://www.generalguitargadgets.com/pdf/ggg_sw_aby3lg_lo.pdf
On the diagram it shows two optional 100 K resistors on the input jacks. I can't seem to find out why those resistors an optional and what purpose they serve. I'm gonna be running the box on a 9 V DC power supply so I will not be using a battery.

those are probably included as "bleed off" resistors, to bleed off stored charge on input resistors for other pedals in the chain that may not have their own, to avoid the Pop

Thanks for the reply Garcho.
