Help! Will this wiring schematic work?

I want a middle pickup on a three-way switch that i can add in on the neck and bridge with push pull pots. All three pickups are single conductor. Will this work?

This schematic is the result of an existing schematic manipulated in Microsoft paint.

Re: Help! Will this wiring schematic work?

In this setup you would have to pull "2" switches/pots. That seems like it ok would get confusing if you was trying to get a certain tone on a single part of a song. Is there a way to put a micro single pole switch in this configuration for just the single coil pup?
 
Re: Help! Will this wiring schematic work?

The middle pickup only needs to be connected to its dedicated on/off switch and, thereafter, to the output jack. Its output level will be governed by the volume pot of whichever pickup is selected at the time.

NOTE - The middle pickup will either be fully on or fully off. There would be no way to blend it relative to the other pickups - nor them to it.

I had visions of it being an attempted Alvin Lee Gibson ES Thinline circuit.
 
Re: Help! Will this wiring schematic work?

I see a couple of potential issues...

  • You should only need one push-pull to activate the center pickup
    • Choose one or the other, it will be much simpler, then run it straight to the output jack
  • Your center pickup does not have a volume or tone control
    • Maybe not a big deal, but you should go into it with eyes open. My own H-S-H has a single master volume and two tones (Neck & Bridge). I have it set up with a P-P to activate the center pup, which goes straight to the master volume, eliminating the ability for the center pup to have any controls. I don't miss it, though. I think the extra volume and brightness on the center pickup helps to offset its lower output compared to the humbuckers. As an extra option, I used the other push-pull as a cut switch for the neck & bridge pups so that I have the option of running only the center. If you want to do that, I can help you with the schematic if you like.
      [*]You could, if you like, go to a master volume and three tones (one for each pickup) or three volumes with a master tone.
Edit: Sorry, Funkfingers, if I rehashed some of what you said... you posted while I was still writing mine! It seems we're both on the same page, though.

Funkfingers, if I rehashed some of what you said.

No worries. I stole most of what I posted. (If I have seen further, it was merely because I was standing on the shoulders of Ted and Leo.)
 
Re: Help! Will this wiring schematic work?

It's an es-339. I thought about a mini on/off switch but i figured this schematic would allow me to adjust tone and volume while its engaged. I just would be able to blend. Plus, working with an es style guitar, i'm trying to avoid adding more holes to line up.
 
Re: Help! Will this wiring schematic work?

1) Is the guitar in question a Gibson or an Epiphone?

2) Does it have a control cavity cover plate on the back or are you going in the traditional ES way - through the pickup holes?

3) It strikes me as odd that you are highly concerned about drilling small circular holes in the top for mini DPDT switches but not remotely concerned about routing a hole the size of a Stratocaster pickup deeply into the centre block.
 
Re: Help! Will this wiring schematic work?

So with the schematic I posted, the volume and tone of the middle pickup would't adjust with the p-p its attached to?

That's correct. The push-pull switch is a completely different entity from the potentiometer to which it's attached. That's why you only need one.

1. Epiphone.

2. F- holes. It was my plan to just route a single coil sized hole between the humbuckers and use a single pickup mounting ring.

3. My concern is not necessarily drilling in the top. Its more so squeezing more hardware into the f-holes, lol.

Crap. So how should I put it in to have some control over the middle pickup?
 
Re: Help! Will this wiring schematic work?

In the schematic diagram from the opening post, the signal from the middle pickup never passes directly through a volume or tone pot.

The signal from the middle pickup is only affected indirectly by the controls governing the humbuckers because ANYTHING connected to the output jack tip contact will be proportionally shunted to ground as the volume and/or tone pots are rotated towards their maximum resistance positions.

Any blending of the middle pickup relative to the other pickups would require a dedicated pot. This modification will not result in Stratocaster-like sounds.
 
Re: Help! Will this wiring schematic work?

Is this the guitar you are talking about?image.jpg I second what Funk just asked about drilling a tiny hole as well. Just say you decided to do the middle pup, would you have enough room between the neck and bridge pup without having some sort of cross magnetic field interference?

This is the guitar. I have no idea about the cross magnetic field interference. That never crossed my mind.

See Funkfingers' last post, he explained it very well. If you want some blending control over the center pup, consider having a master volume and 3 tones, 3 volumes and a master tone, or possibly employing a dual concentric pot or two.

Okay, So it sounds like to do what i want it to do, i would need 3 volumes, 1 master tone and an on/off switch for the middle to work with the 3-way toggle, correct?

Was that another stolen post Funk? Lol.

Possibly... Although with three volume controls you would not necessarily need the on/off switch. You could just blend the center pickup in with its volume control.
