ROG Splitter-Blend bypass problem

[rody82]

I've successfully built this pedal, and it is working ok. I've made a Mill2 bypass board
for it, and wired it for true bypass. When i'm powering up the pedal the led is always on (no matter
in what position the switch is), for about 5-10 secs. After that the switching works as normally. Seems
like some capacitance is charging up? (10uF output caps are big...)
The problem is the popping sound when i switch. Is this related to the led problem? Any ideas to
fix it? (there's already an 1M pulldown resistor before the output)

no ideas?
