Push-pull volume pot with treble bleed on coil split problem

Hi everyone, I'm about to start a project on my Japanese '93. RG 470. The stock pickups were changed to Evolution neck and bridge with True Velvet single coil. Now I have ordered the V-Treb treble bleed circuit for it, and I want to split the neck pickup using the 500k push-pull pot on volume with treble bleed. But - with treble bleed engaged in both push-pull pot positions. Now is that possible, though I use the neck humbucker very rarely I would like to have a treble bleed in full humbucker and in the split coil mode too?
Any advice with a schematic would be much appreciated!

Re: Push-pull volume pot with treble bleed on coil split problem

Hi Ivan75, and welcome to the forum!

I wasn’t familiar with a V-Treb, but I looked it up and, as expected, it’s just an add-on to the volume control. That’s good news because you can go ahead and split the coils of your neck pickup with the push/pull.

Keep in mind that the potentiometer and the switch on a push/pull pot are completely separate components that just happen to be attached to one another. The treble bleed is unaffected by the switch, so it is always available no matter what position the switch is in.

I don’t have time tonight to get you a diagram, but the internet has tons of diagrams available for using a push/pull pot to split a humbucker.

If you can’t figure it out, just let me know and I’ll see if I can whip one out for you tomorrow afternoon.

Good luck! [emoji1303][emoji41][emoji2]

Hi, thanks for clearing this up for me, it's the explanation I was hoping for. As for the diagram, all I could find is the diagrams that show the treble bleed engaged in split coil mode only. Thanks again!

I'd be interested to see one of those diagrams with TB only engaged in split......
 
Re: Push-pull volume pot with treble bleed on coil split problem

That's it, as far as I know, all the diagrams I've found are showing exactly that wiring. It would be logical that the treble bleed works in both modes but I'm not sure, so I'm still looking.
So mine would be:

5-way switch with push - pull volume-when pushed down (or off)

-Neck humbucker
-Splitted neck + middle single RW/RP
-Middle only - I don't ever use it
-Middle + splitted bridge humbucker
- Bridge humbucker full.

Now, all I need when the PP pot is ON is the neck coil split, everything else unchanged. Plus the treble bleed working in both PP modes.
This should be simple but I'm not very experienced in wiring and I want to make it right... If anyone finds a corresponding diagram, please post it here, thank you!

Re: Push-pull volume pot with treble bleed on coil split problem

Treble bleed components from my knowledge spans 2 lugs of the volume pot. Hopefully this is the sort you are referring to.
As the coil split wiring affects the pickup signal before it gets to the pot or switch (whichever it gets wired to), treble bleed as I described cannot do anything but affect whatever signal passes between those lugs......however many coils are involved in generating it and however many switching operations happen preceding that.

Your 5-way switch type wiring has the pickups and their coil cuts operating even before the switching/pickup selection. Then it passes to the common lug to the volume pot. The treble bleed then works to pass the treble in that signal through to the output.

Ok, what I thought, exactly, works in split or full humbucker.
This is the treble bleed circuit I mentioned:
v_treb__93588.1470693258.500.400.jpg

Two points are soldered to volume pot lugs.
Little pot with cross allows regulating the amount of highs which pass.

It is cool but still, to be put in the Strat I have to pull two leads from the volume and fine tune it, removing the strings and cover annoys me... Bummer. On the Ibanez with no cover plate I can do it way quickly. Still, it is more convenient than trying out dozens of different caps, tidious.

Re: Push-pull volume pot with treble bleed on coil split problem

Attach it on leads that are long enough for the module to hang outside of the pick guard temporarily. Then you can put the whole thing back together with the treble bleed easily accessible, adjust to taste, then take it apart, secure the module, and put it all back together only one more time.
 
Re: Push-pull volume pot with treble bleed on coil split problem

that is pretty cool! never seen one of those before but seems like a good idea. i usually dont get along with treble bypass wiring cause its too much and does weird things to the taper

I hope that won't be my experience...
@BriGuy1968
Yes, I know. I saw some reviews, sounds good, I hope I won't be disappointed.

I need help, could someone please draw this diagram with push/pull on volume instead of tone?
Besides exchanging the caps what else should I do? I would also remove the split ability on bridge pup.
Thanks!

Re: Push-pull volume pot with treble bleed on coil split problem

The switch in the pushpull is separate. So simply wire up everything just the way you see it.....the only thing that is different is that the location of the switch is a different pot. The only connection that changes is the ground from the pushpull lugs goes to the volume pot back/casing - but its still the casing that the switch is on.
 
Re: Push-pull volume pot with treble bleed on coil split problem

But what about the caps? I don't think I understand that, sorry, You have just described the situation just the way it is on the diagram right now.
''The only connection that changes is the ground from the pushpull lugs goes to the volume pot back/casing - but its still the casing that the switch is on.'' It's just the way it already is, right?

The whole thing stays exactly the same. You wire everything up where it says. But the 6 lugs of the switch are now above a different pot. As I have already said they are entirely independent of their physical location - so the location doesn't matter. The ground from the lugs goes to the nearest pot cover.
 
Re: Push-pull volume pot with treble bleed on coil split problem

Ok, thanks, I'll try.
The whole thing seems less and less nice to me, I just doubt it's going to sound good enough to be worth my while. In the end I think I'll change the neck Evo and middle pup to DiMarzio Fast Track or some other hum cancelling single. This is going to be just too weak and kind of ''slim'' sounding. We'll see.
 
Re: Push-pull volume pot with treble bleed on coil split problem

Ok I did it. First of all I'd like to thank everyone who helped me with this! I decided to leave it the way it's on the diagram, push/pull on tone. Just for the record again, it's Evolution neck and bridge with DiMarzio True Velvet RWRP in the middle. Volume pot is a bit loose, tone pot is smoother and feels better, but they both work nice.
Well on the sound I've got, first of, neck is split to active outer coil, 2nd position is also outer neck+rwrp middle but the bridge is split to active inner coil. I think this is exactly what I would choose, not too bright on split bridge and just about enough bright in neck. I mean overdriven/heavy distorted sound. Clean is good enough in both position 1 and 2 but, as expected a bit thin and quiet and not even remotely solid as a Strat would be. Maybe using it in a separate amp channel is the best way to get the most out of it. Can't try that, right now, my Laney needs some serious service. Anyways, what I really like is split outer neck heavily overdriven /distorted. Overall of much better use with distortion.
Now I'm waiting for the black 3ply pickguard to arrive, knobs are replaced with black plastic... Thanks again all of you!
