Hi. I keep running into this really annoying problem on my 4-way Oak Grisby switch where the neck pickup keeps bleeding through the guitar signal by a very small amount when I switch the bridge pickup all by itself. What's strange is that the amount of neck pickup bleed through I get is only a fraction of the neck pickup's maximum output. But it's undoubtedly colouring the tone of the bridge pickup when it shouldn't be. I just want the pure bridge pickup by itself darnit. This is the diagram I'm using. One difference however that I swapped the hot white wire on the neck pickup for the black wire. If I used the white wire per the diagram above, both pickups would be out of phase. Swapping the white and black wires around fixed it. another thing of note is when I'm on series mode, if I disconnect the hot of the bridge pickup, even though I'm expecting there to be zero output from anything, I'm still getting that tiny fraction of output from the neck pickup. Also, when I select the neck pickup by itself and I tap test the bridge pickup, I get no output. The problem is solely with the neck pickup (in this case a Lollar Royal T) This is weird and very confusing. How do I fix this? Thanks.
