Guitar Schematics Question

Hi.

This is my first post in this forum =)

Sorry it's not anything useful.. but a question.

I've recently bought 2 humbuckers. (Benedetto A6)

I don't want to drill any holes onto my guitar nor do I want any of the holes unfilled or anything not doing anything to change something.

I have on my guitar at the moment.

2 Stock Humbucker Pickups
1 Piezo Pickup connected inside the bridge.
1 3way toggle switch.
1 3way DPDT on/off/on mini switch which selects between humbuckers/hum+piezo/piezo.
1 Master Volume pot for the humbuckers.
1 Master Tone pot for humbuckers which coil-cuts both humbuckers using push-pull.
1 Stacked Pot with Piezo Tone and Volume.

My Plan is to Change this in to.

2 New Humbuckers
2 Volume pots for each humbuckers.
1 Master tone pot for both humbuckers.
1 3way toggle switch between humbuckers.
1 On/On DPDT miniswitch for Series/Parallel switching for Both the humbuckers.

I'm going to take out the Piezo Pickup altogether because I never use it.

Anyway, I was just wondering if anyone on the forum can verify that this would be possible.

And if so, has anyone seen a wiring schematic for this kind of circuit?

Any help will be greatly appreciated.
 
Minus the DPDT switch, the wiring diagram you described is identical to a Gibson Flying V or Explorer.  The DPDT switch, or switches, would simply go between the pickups and the volumes.  As far as an exact diagram for this, there are so many out there I'm sure this one exists. 
 
Hi, Thanks for your reply.

I understand it is the same as an gibson flying V.

But the Series Parallel Schematics existing (that i've seen) use two switches (or push pulls) for each pickup.

What I need is something with one master switch for both pickups.

Thank you very much
 
I don't believe that can work, because when you wire each coil of the humbucking to a switch, you're also wiring them to each other. I mean, you're hooking the north coil of the neck pickup to the north coil of the bridge pickup, and the south coils together, aren't you? All of "our" wiring info is stickied together, here:

http://www.unofficialwarmoth.com/index.php?topic=281.0

It sounds to me that what you want is close to the "Jimmy Page" wiring, which uses push/pull pots with DPDT's on the knobs:

That comes from the Duncan"Menu", here:

There's a lot of things to choose from, for sure....
 
Hi thank you for clearing that out..

can you please suggest me some of the tone change options with just one toggle switch but alter both pickups?
regardless of what type of switch it is.

Thank you very much
 
Just to make sure it's clear to the OP:

1. If you want to switch the 'both coils on' from the normal parallel to series modes (chaining the humbuckers together to create a super bucker) that is easy to do with one switch.
2. If you want to switch each pickup from being wired in series (with itself, the normal humbucker way) to being wired in parallel (with itself) you need two switches.
 
It just takes an SPDT switch to coil split, so you could do both pickups with a single DPDT switch since both sides are isolated.

If you didn't mind using (2) DPDT switches or push/pull pots, this is actually the original diagram you asked for.

In normal, ideal humbucking mode, a humbucker has two equal coils that are wound in opposite directions.  The pole pieces of each bobbin are making contact with opposite ends of the same magnet.  In series, this is a full fat sound.  This is also referred to as series 180 degrees out of phase.  In parallel, it is still humbucking but the sound is thinner.  Whether or not the parallel sound is useable is a matter of preference.  Chances are this would not be your default, go to sound but would be handy for an intro or bridge of a song IMO.  When most think of a humbucking tone, parallel ain't it.  When humbuckers come with only two leads, 99.99% of the time, they are series 180 degrees out-of-phase.  A DPDT switch is required for this mod, and it requires one DPDT per pickup.

A split coil can be achieved with a SPST switch, one per pickup, but a single DPDT can do both and have them be independent.  However, if using a single DPDT instead of (2) SPDT, it would limit your options.  You would have to have both hums or both split (or one and one depending on the wiring).  You couldn't do neck single and bridge hum, neck hum and bridge single, neck and bridge single, or neck and bridge hum.  For this reason, I'd do 2 SPST or push/pull pots.  The split coil sound, although a single coil, lacks the sound of a true single coil and is best used in conjunction with another pickup.  

Here is a coil split diagram.  It's using a DPDT, but only half of it so it's effectively an SPST.

Q: Whats the tonal quality of the both coils on mod?

A: Depends on what else is happening...  :icon_scratch: Seriously, you have to try a lot of different things for a while to start getting where you're going. There's no substitute for it. Let's try this again:

Q: Whats the tonal quality of the both coils on mod, plugged into two '69 Marshall no-master volume 100w heads chained together into 8 JBL D120F's?

A: Well, pretty darn good.... :party07:

Q: Whats the tonal quality of the both coils on mod, plugged into a $99 Line 6 amp?

A: Even better! Just poke the button labeled "'69 Marshall".... :laughing3:
 
Hey Thank you very much for your opinions.

I have decided to go with coil-cutting.

And I tried to make changes to the Schematics existing and would be very happy if someone checked it out and

check it would work.

Again Thank You

Haha.. Very Funny..

By tonal quality I actually meant the characteristics of the tone.. not how good it is.

That would be tonal *qualities*

Can anyone make sure this is the right wiring for coilcuting?
 
At first glance, I'd say no.  Currently I'm busy with a few projects and I've got prior engagements this weekend.  I'll draw you a correct one if you can give me a few days.
 
Hi.

I can't thank you enough for offering me to do a scheme for me..

But can you just point out whats wrong with it? As all my parts have arrived today and i'm itching to start :blob7:..

Although I understand it would be better to wait than screw up..
 
I went ahead and made one.  It's taking forever with photobucket right now.  To answer your question, the neck volume pot in parallel with the pot and the switch and even the switch terminal choices is what was throwing me.
 
It may be my computer, or this is a heavy traffic time for Photobucket and they're having bandwidth issues this morning.  I'll get it posted in a few hours.  In the meantime there's other stuff in the assembly you could probably get moving on.
