TB-4 JB + SH-2N Wiring idea

Re: TB-4 JB + SH-2N Wiring idea

Is there room for pots where the switches are?
I just did the same Pups with 2 vol, 2 tone, and a 3 way switch. I put push/pulls on each of the pots and wired it for Series/Parallel/coil tap. That gives me 22 tone settings. I can use either pup by itself. I can pick which coil to use when in single coil and get some good blues tone with the neck single coil. Great LP blues tone with the single south coil at the bridge and the HB in parallel at the neck. Basically I can use any coil or combination that could be conceivably possible.
You don't need the 3way switch if you have a volume for each pup. You can just turn them down.
I have a schematic but apparently I'm too new on the board to post links so my replies don't show up if I do. Never worry, if you want it I will find a way to get it to you.

Re: TB-4 JB + SH-2N Wiring idea

just post it here I'am also really interesting - I love peaple with supernice outstanding and out of mainstream wiring ideas.
Now something about the pups double volume - It is nice, but it needs more time to switch it down or up - than using 3 way togle - how do you think mlimbolimbo??
what also do you think about changing one of your volume to the pickup selector left pot Neck, right Bridge, middle HOT (that will give you really smooth move - but you need to use linear (so tone) potencjometer).
that was some crazy ideas from me - some others crazy ideas?????
I wish we will receive

Good point. I just played around with mine without using the 3way. First problem is that each volume affects both PUs when everything is coupled. With that in mind, if you don't have a 3way, you may as well use only one volume. So, I suppose you could put a 3way in one of the holes. That would cost you one push/pull. I'm pretty sure, since we only use one side of each DPDT push/pull, we could still do the second coil tap for either single coil choice or series vs parallel. That will take some thinking. It may make more sense to use toggles. I would hate to lose tone control for the individual pickups though.

Here's the schematic for 4 Push/pulls and a 3way.

Re: TB-4 JB + SH-2N Wiring idea

Ok. I looked at SD's schematic for 2 Humbuckers, 1 Volume, 2 Tones, 3 Way Switch, 1 Push/Pull. If someone were to combine the post switch volume on this one with the wiring for parallel/series in mine (posted above) I think you could have 1 Volume, 2 Tones, a 3 Way Switch, and plenty of flexibility to wire 3 push/pulls for your preference of coil tap or Parallel/Series control.
You loose some functionality with only 3 push/pulls. For example: If you were to combine the single/humbucker coil controls on one switch by using one set of poles on the DPDT switch for each PU separately, you would be selecting both single coils with one switch pull. If it is wired to use both North coils, that is what you will get... I believe, though, that since the other push/pulls are in the same circuit, pulling either would engage the parallel option for the connected PU. One parallel HB and a single coil is a pretty good blues tone out of this PU combination, I think.
The other thing I think you lose with 3 switches rather than 4 is the ability to use a single coil in combination with a HB in series mode.

Have fun stoimin the castle.

Re: TB-4 JB + SH-2N Wiring idea

Tommorow i suppose...
You will see something that will really take our discussion at higher level of curiosity - mlimbo.
And as always any suggestion will be taken into real consideration. I hope my new project of wiring will meet a lot of possitive comments from you. Btw: it is so interesting that i will do the same with one of my old guitar.
Till tommorow

Re: TB-4 JB + SH-2N Wiring idea

I did a bad bad thing and spent a bit of time sketching this out and tracing the wiring. Attached is a schematic of 3 Push/Pulls and a 3Way. I can't try it here, but I traced the signal through each setting and it looks like it will work. Compare it to my other schematic that does work and you should agree.

Here are the notes:
Volume and Tone Push/Pulls down = White (Yellow in the drawing) and red are connected for both PUs, putting both in series (normal mode).

Volume Push/Pull down and either Tone Push/Pull is UP = The North coil of the associated PU will be cut and only the South coil will be active.

Volume Push/Pull up and either Tone DOWN = the finish (F) of the South coil is disconnected making only the North coil in the associated PU active.

Volume and Tone Push/Pulls up = PUs in parallel.

Examples (all with 3Way in center position):
1 - Volume is up and Neck PU Tone is up = The Neck PU will be in parallel and the South coil of the Bridge will be active.
2 - Volume is up and both Tone switches are up = all PUs in parallel.
3 - Volume is down and Bridge Tone is up = Bridge South coil active and Neck HB in series (normal) mode.

Have fun. I will try and check in tomorrow.

Re: TB-4 JB + SH-2N Wiring idea

re-draw this schema - Iam sorry but You indicates so many strange grounding connection that I have lost there.

Re: TB-4 JB + SH-2N Wiring idea

As I said guys!!
First schema of our new project: (preliminary research)

this gives as many selection posibilities and also kill switch mode in some positions
- spliting of both north coils. (push pull)
- parallel of neck series of neck (push pull)
- parallel wiring and series wiring both pickups together (mini)
- three way toggle of pickups.
waiting for comments

Re: TB-4 JB + SH-2N Wiring idea

I figured out how much position and where we have:
14


- uff some are wird and crazy

regards,

I include ground wires in my drawings.
I'll see if I can get to it next week. In the mean time, this should clear it up. Anything that ends at the side of one of the switches is grounded to that switch. For example each Green wire from the pickup connects the start of the South winding of the pickup to the top terminal(s) of the switch attached to the Volume pot. A lead from that connection to the switch must also be grounded to the switches cover.
Any of the grey (pencil) lines are ground wires. All of those will terminate on one of the switch covers except the one that goes from the 3way to the jack.
In my PRS the wires from the 3way to the Pickups are shielded. The ground wire therefore runs with the red or green wire from the switch to the Tone pots where that ground will be soldered to the cover on the switch.
I also included a tone circuit for the Volume that prevents the highs from bleeding off as you lower the volume. That is a 100K resistor and .001 uf cap in parallel. It works and is worth the extra few minutes of soldering.

I hope this clears things up a bit.

mlimbolimbo it seems that you can do your own thread in which i can help
make your own thread and i will draw for you your own diagram
this is the best solution

I don't need the drawing. Was just offering a possible solution to the original question. If you want to detail the drawing and upload it, you are welcome to.
I will point out though that most schematics are lacking in detail on the ground connections. An inexperienced builder can easily turn that lack of knowledge into a ground loop or fail to ground properly all together.

Re: TB-4 JB + SH-2N Wiring idea

Once again ME
Belcik - You will have a problem with switching maybe....
Check if this can be possible...
If not we wiil do some other things....



To Mlimbolimbo:
Are You using SD - pickups????!!
If Yes Your diagram is wrong
IF Not - at some points Your diagram is also wrong.
Check it and redraw it

Re: TB-4 JB + SH-2N Wiring idea

A mini toggle usually needs a smaller hole than a pot. A knob right next to a mini switch is highly uncomfortable, while two minis next to each other are ok.

Re: TB-4 JB + SH-2N Wiring idea

Hey you all.

I start collecting items.

I do not think that putting pot ot the mini toggle hole will work. I will measure and check.

Thank You all for help, possibly next week I will start soldering. I will keep You informed on the progress.

One question. 3-way toggle is somewhat not clear for me. KnifeR was suggesting the 3-way 4 pole; do you have some example how to connect it in this type of configuration?

Re: TB-4 JB + SH-2N Wiring idea

I was sugesting 3 way 4 pole but finaly I done it with normal 3-way
im just afraid about 3 way, and mini close to each other - this can bring you some obstacles....
but it just my Idea. - BTW - 3 way toggle has also bigger hole so it is just the same .

I could be wrong but I would appreciate you being specific about where you think it's wrong. To be clear, this is a mod of a schematic that I have in use in my PRS. Where it is modified is that where I have 4 Push/Pulls, here there are only 3. The coil taps are both on the same switch (different sides and separate). The tap is not traditional in that instead of shorting a coil, we cut the circuit. This came from another SD schematic.
The other change from my working circuitry is that the volume is moved to the jack side of the 3-way switch so that one volume can be used for both PUs.
Also, white wires are yellow in my drawing.

Belcik,
Really look forward to seeing what you come up with. It's quite a challenge coming up with something that will work in that small space. Keep us posted.
