If you’re not good at soldering, (don’t know if you are) you may have solder making conections in places it shouldn’t.
Or you may have fried the switch or pot(s).

Try just connecting the bridge pickup only.
If you can get that sound right, you might be on your way.
Then add in one pickup at a time making sure things keep working correctly.

Thank you, thatīs correct thatīs how itīs wired so Iīm not gonna tamper with that, Iīve got enough on my hands already.

So hereīs an update;

I found this diagram which seems to do exactly what I want, so I wired it up accordingly;

http://www.dimarzio.com/sites/defaul...s/rg320_pp.pdf

The issue that seems to carry on; very very low output with a loud buzz, touching the inside of the cable plug seems to quiet it a bit, as if I was grounding it with my hand.

The positive outcome; all 5 positions of the switch are working accordingly.

The strange thing; If I plug the cable all the way in I get the very low output issue but if somehow I manage to unplug it just a bit without withdrawing it completely the output now comes at full and it gets loud but the buzz also gets even louder

What do you guys think? Iīm starting to suspect that I just fried my volume pot, Iīm thinking about getting a simple 500k volume pot and try to start over...

Feeling kind of sad this morning, I thought I had it worked out.

Take the nut off the jack and slide it on to the wires so you can pop the jack out or at least rotate the jack.
You'll see one of the legs is on the outside edge of the jack, near the threads.
The other leg will be in the middle of the jack.

The ground wire should be attached to the bottom or side of one of the pots, not on any of the three legs.

By saying "ground" you mean that it has to connect to the first pin of the volume pot? along with the green and bares from the pickups?

How do I know which is the outside leg? both look exactly the same...

Understood, thank you, though the question still stands; could it be that I need to reverse the two cables coming from each of the tall legs on the jack?

Thank you good sir, it was working perfectly with the 3 way switch, so Iīm pretty sure itīs fine.

Came across more interesting information on the internet, please take a look at this diagram;



Whatīs interesting about it is that, if you take a close look at the jack (which by the way has three legs, two large ones and a short one) the cable that goes to the middle pin of the volume pot is coming from the short leg of the jack! But on my diagram itīs coming from one of the large ones and the short one is not used... Should I try this too? What would be the difference? Why does the jack have three legs?

Thank you for your help!

Re: Can you help me complete my diagram? (Push Pull volume pot Coil tap HH)

Update:

While searching the internet I came across the story of some guy who wired two dimarzio humbuckers exactly like mine to his S420 with a positive outcome, he was kind enough to post his diagram and whatīs interesting is that the red and green cables are reversed compared to my diagram;



Also the black and white cables on the neck pickup seem to be reversed.

I will definitely try to wire it this way and see if the buzz goes away, but can someone be kind enough to explain to me whatīs the difference? All I could find regarding colors is that, in the case of dimarzio, RED=North Start=Hot GREEN=South Start=Goes to ground along with the bare cable.

If thatīs the case then why did this guy wire his guitar with the red and green cables reversed? Should I even try this?

Thanks in advance for your kind guidance.

Re: Can you help me complete my diagram? (Push Pull volume pot Coil tap HH)

If you look at the jack, the outer leg is the ground.
The inner leg is the hot.

The trem, and both pots need a ground wire attached to them.
The pots have a ground wire attached to the flat bottom or side of them.
The trem has a ground attached to the claw by the springs.
Sometimes a switch will have a ground on the side of it or on a leg, depending on the wiring setup.

If your jack worked before, it's probable okay.

If you get really stuck, hook up only the bridge pickup and see if you can get it sound right before you add in other pups.

Thank you. So here's the thing; I wired everything exactly like the original diagram I posted says (RGT42) but ignoring the bottom 6 pins of the volume pot which means I'm only using the top three and the body of the pot and here's what happens;

When I plug my guitar to the amp I get a VERY loud buzz/hum even on the clean channel; this is true in all 5 positions of the switch, then if I move or try to push the cable further into the plug the hum kind of goes away but I get a very very quiet output to the amp, almost inaudible but the output is actually there.

I checked to se if I have some loose cables coming from the plug but everything seems to be in place, maybe I got them reversed? I can see that there are two cables coming from the plug and maybe those are reversed?

One last thing; I did plug the cable that comes grounded to the back of the tremolo to the first volume pot.

Any further help would be kindly appreciated.

what Sebastian said is ideal in that get the 5-way working fine (as per the first diagram you posted). then do the taps. But really it's moot since you want the taps and it's easy to go back to the RGT42 wiring.

Remember the 5-way (or 3-way it's moot) just sends signal to the volume switch (and thus coil-splitter).

If you are using a 5 way switch, the JS diagram won't work for you.

Get the 5 way switch working correctly before you add in the wires for the coil tap.
Then let me know how you have the switch wired and I'll tell you how to add in the coil tap wires.

Adding a coil tap to any setup is easy.
Run a ground to the push / pull pot and then to the black and white wires, if your using a Dimarzio 4+1 conductor pickup.
(That’s if the black and white wires are soldered together or on the same spot on the switch.)
If the black and white wires are not together, you’ll need to see which one you want grounded out by touching the ground wire to the back and then the white wires to see what effect you want or like better.
Thank you Sebastian, I'm pretty sure it is the same switch.

I beg you to specify much more clearly what you mean, remember I'm a complete newbie; what do you mean "run a ground to the push pull pot"?

Yes according to the new diagram based on the JS guitar the black and white wires are both goin to run together.

That would coil split positions 1/3/5 (pull up to split, if it's on). If it's too comples you can always call Dimarzio and have them provide instructions for wiring the push/pull coil split for those positions (when both coils of the humbuckers are on).
Thank you.

Ok so analyzing this diagram what I basically have to do is:

1.- solder both black and white cables from the neck pickup and solder them to the volume push pull pot exactly like in the tone pot of the diagram.

2.- unsolder the black and white cables from the 5 way switch and solder them to the volume pot instead.

3.-solder the left middle pin of the push pull to the body of the pot.

4.-solder the right middle pin of the push pull to the body of the pot.

I will try to do exactly that and comeback with the results, thank you very much for your kind attention.
