Hello I just received my Seymour Duncan pickup system along with my slime green Duncan Invader. I have followed the diagram for my setup bridge pickup with 1 volume and tone. But I go to plug it in and nothing. Is their possibly something I'm missing or may be wrong? I had help with someone with electrical experience or would I be better off to go get my liberator professionally installed then if I decide I don't like the Invader to go with something else I can do the pickup install myself.
