Wiring issue, individual volume pots not working as intended...

(The intent is to have 4 single coils from 2 humbuckers, and individual control for all 4 at any given moment, and be able to mix any together in any amount)

Ok, Here's how it's wired atm:

Hot from Input-Tip goes to center switch position

Then from there two leads are twisted together on one end and soldered onto the "neck" position of switch
Two other leads are twisted together on one end and soldered onto the "bridge" position of the switch.

From there each individual hot lead is sent to 1 of the 4 volume pots (which are actually two concentric pots - CTS 500k/500k on both)

I have the Neck's North Finish going to the "first" lug of one pot in the stack, and the Neck South Start going to the other "first" lug on the other pot in the same stack.
The bridge is done the exact same way.

The North Start and South Finish are wired together with the pickup ground and soldered to the base.

Both pots from a stack (both stacks are wired the same here as well) have individual jumpers from the ground (or "third") lug to the base.

The bridge ground (not pickup, but actual bridge ground wire) is soldered to the neck concentric pot base, as is my copper shield's last jumper wire. (I connected each cavity's copper shield to one another with wire).

The "ground circuit" goes from the switch ground, to the neck base, to the bridge base where it connects with the sleeve ground out on the same solder spot as all the bridge pot's grounding wires.


What is the problem?

Say I switch to the neck position of the switch. If I want to turn on just the south coil, I have to turn on the north coil a little bit in order to have any signal at all. The same goes if I just want to turn on the North Coil of the neck humbucker pickup.

The same applies for the bridge humbucker.

if I switch to center, all 4 pots have to be on just a bit for any of the other 3 pots to work...

I want to have individual control of each coil, without having to turn on any of the other 3 pots. But the reason why I didn't go with another switch with more positions, is because seemingly I shouldn't have to. I should have individual control without having to switch. I also want to have the ability to blend in any of the other single coils from my humbuckers into the mix (if you will) for complete tone control here... yet it doesn't work that way in this wiring for some reason.

Anyone have a solution here? And yes, I know that this gives me parallel wiring for the humbucker, I am well aware of this... this seems to be the only solution I could come up with that wouldn't end up with "out of phase" occurring when both pots from a single stack are at 100%... (if I wired it like a standard humbucker, but put the ground with the red and white and stuck that to base instead of green and ground going to base... I'd end up with this phasing issue...)

Anyone know of a way to use this idea of 2 concentric pots for individual control of each single coil, with parallel wiring here, using what I've got here?


I can go and get me a pair of Triple Shots in a few weeks if I have to, but I wonder if I can do this without those switches, and just these 4 pots and a 3-way switch? Is this even possible?

What all is possible with what I have if all 4 pots are just standard pots and don't have the additional components for making any of them a tone or what not)?

Thanks in advance for any help here.
 
Re: Wiring issue, individual volume pots not working as intended...

I think you need to wire up your volume controls for independent operation. Just about every guitar schematic is dependent controls....with two pickups selected if one pickup volume goes to zero means there's no sound.

From memory you swap the hot lead and the wire to the selector switch locations on the vol pot.

What? I need a little more information on what you mean here? Yea, that's the problem I have if one pickup's volume goes to around 6% or less (about) it goes off...


Here's a schematic:

You need to rewire the volume pots. The red leads that go to the switch need to be on the LH lug for each one. The wires from the pickup coils need to go to the middle lug.

Ok, I will try this at when I get home tonight (bout to take off as I'm typing this for work). Can you elaborate on why I'm switching the two? Usually hot goes to the wiper/middle lug... I mean I get that we are working out the kinks in this, it's just that I am curious as to the why involved here so that I understand it on a deeper level than "it just should be wired that way", gotta learn the whys and what not for everything as I go so I don't make the mistake(s) again :) . Learning is a constant process no? Thanks for your help in this.

(usually, the switch is where the pickups go (the outter two lugs of the switch, hot goes center), but I'm taking the switch out of that part of the equation to try and allow a blending of the 4 single coils...)

The independent wiring works by not allowing a pickup to be grounded out by another via the wiring that connects them through the switch lugs. I think it is due to the lugs for the switch being on the wiper that this effect comes into being. Having the pickup on the wiper lug I think isolates the output on the outer from the other outer lug which is the grounded lug.

I'm finally home, and not only trying to warm myself up... but warming up the soldering iron ;) I'll try this out and let you know if it worked or not. I'm thinking if this doesn't work I'm just going to break down and buy the triple shots.

And as far as all that goes, you're saying the North Finish and South Starts need to be on the middle lugs (lug 2) right? and the hot needs to go to the LH lugs (lug 1)

IT WORKED! THANK YOU! HOLY CRAP DUDE! THANK YOU SOOOOOOOOOOOOOOOOOOOOOOOOOOOO MUCH!


I could kiss you! ugh... er, well of course i won't but you get the idea...!
