HELP: My neck pup still outputs when vol/tone controls are all the way down

[sparkplug]

I just modded my JB/Jazz guitar. I have 2 on-off-on mini switches that select which coils on each pup are active, and I have a push-pull pot for the tone control that I use to reverse the phase of the bridge pickup.

The hot output of the mini switch for the neck pup goes directly to my 3-way blade switch, which of course outputs to L1 of my Vol pot.

When I roll my Tone and Volume all the way back, I still get (very low but clear) output from the neck pup (the tone doesn't have to be rolled all the way back; when the tone is wide-open, I still get neck output, it's just not as loud because less bass).

I think that my blade switch is the root of this issue because my bridge pup doesn't have this issue, and when I switch from bridge position to middle position, and rarely from bridge position to neck position, the neck isn't outputting but it stutters back on, like a short/broken circuit.

I have tried resoldering the neck to 3-way connection and it did not fix the problem.

Does anyone have an idea why it does this? And how I can fix it? I can provide more information if necessary. I almost sorta know what I'm doing, kinda.

Need to see diagram you were following and clear pictures of your complete wiring. Are you sure your mini switches are indeed on-off-on?

Yes, my switches are On-Off-On and they function as designed. I got them from guitarelectronics.com. To clarify, the volume control does affect the neck pickup, there is still some output when the volume is off though, as if the volume were at about 1.5.

Here are some diagrams I used. I couldn't find a concise one with everything I needed.

probably can't get you clear pictures of all of the wiring because it's very very busy in that cavity. I can get you some if you have to have it. But I don't think that one would be able to tell from just looking at pictures? I feel as though you'd have to see for yourself to make sure that there is nothing touching that isn't supposed to, and everything is soldered properly, etc.

The Duncan drawing shows both phase and pickups in series. If you have the pickups in series, that will defeat the selector switch. How did you connect the bridge phase and coil splits? What order, what lugs, etc.?

I set up the mini switches using only one column. looking into the cavity, on the mini switch for the neck pickup, the green/bare wires are soldered to the left throw and that throw is wired to ground; red and white wires are wired to middle throw; black (north start) is wired to left throw, which is then wired as the output, to the right input of the 3-way switch.

The bridge pickup is the same thing, except the hot output of the mini-switch is wired to the left middle throw of the of the push-pull pot (which outputs from bottom right throw to the left input of the 3-way) instead of just going to the 3-way switch input; and the green wire is soldered to the right middle throw of the push-pull instead of being wired with the bare wire on the mini-switch. That reverses ground/hot so the phase is reversed.

The 3-way switch outputs to the left (if you're looking at the pot with the lugs at the bottom; the right lug is soldered to its ground) lug of the volume pot.

The volume pot is wired from left lug to right lug (same orientation as volume pot) of the tone pot. The volume pot outputs to the output jack via middle lug.

Is all of that clear and concise? makes sense in my head.

Thank you for helping me, sorry for the late reply.

Here are two images of the wiring, but they may be unclear and unhelpful. I use white and red solid-copper stranded wire for my wiring, and heat-shrink. probably hard to follow and most angles are obscured

Is everything shielded? The reason I ask is I had something similar when one of the lugs on my volume pot on a push pull was touching the grounded shielding. Always worth checking if your wiring has excessive bare wire that could be causing an unwanted path to ground or unwanted hot connection.
