There might be a problem with the line spiltter I built from Waldos site. I used a Carling SDPT footswitch in place of the toggle and the bypassed output still has a very faint signal. Barley audiable through an amp on 10. Is this normal or is there such thing as a leakey bad switch?
I had the same exact problem with the first one I made too. It needs a ground to a DPDT foot switch or toggle switch like this diagram. Just add the grounds connecting all the in put jack grounds to each other.
