I understand the Y cables used to run two pedals from one output are ground lifted, and that the two pedals need to share an audio ground to help prevent noise. What if the two pedals are seperated by another pedal? In other words I have two loops (one clean, one gain) and use a Boss LS-2 to select between the loops, what if one pedal is in the clean loop and another is in the gain loop, is the ground connection broken? Will this cause hum/buzz/nasty ground noise?
