I have a Gretsch 5232t. Wonderful guitar for what it is. When I got it, I had a tech replace all the wiring and pots and a more fine tune setup. He did the setup beautifully, but totally flunked on the new wiring. I had him re-wire/solder some wiring on an old Starfire III...and he did a great job...so I took the Gretsch to him.
The Chinese Gretsch has a tad different wiring than normal...with a master volume, volumes for each pickup and a master tone. Also the 3 way pickup selector switch with a treble bleed on the master volume.

When I got the guitar back, the volumes were not working properly and would affect the other, etc. I took it back... just different issues again. For the 3rd trip, he then took the guitar to another tech and paid for it himself, but this new "wiring guru" was stumped too. For instance...on the neck pickup only... the volume on the bridge pickup will shut off the neck pickup, when totally turned to zero. Things of that nature.

I have pulled the schemetic off the internet, provided it to the tech(s)... and then finally tried myself to resolve the issue, only to create new.
It doesn't seem like rocket science...but something is amiss. I can follow schematics, can solder, but admittedly am beginning to learn this. I have wired Les Paul style guitars with no issues. The 3 volume controls, espeicially with the master volume in series, seems to be the issue...not to mention the master tone stuck in there too.
I really never use the tone, so just thinking of taking that out of the circuit completely...but then my OCD with an unused pot/knob would bug me.

Do I need to show pictures of the guitar's current wiring, potential schematic, etc?... or what's the next best move?

If you could link the diagram and maybe a couple of pics that will definitely help, there's some sharp eyes that may spot a mistake with the wiring or something.

Here is what I believe I gave to the tech(s). The 2nd is obviously the TV Jones, which I presume is just fine as well. Neither are showing the treble bleed on the master...and that's not really necessary imo.
I'll get guitar pictures soon. All 500K CTS pots now too..... (I believe)

Skip the master volume and tone, they come after the switch.
There are two ways to wire a volume pot the modern way gives you interactive volumes the other way gives you independent volumes. In the middle position turning one pot off will kill the sound with interactive wiring.
Have a look at this diagram and check how your volume pots are actually wired.

you want them wired as independent volumes, swapping the wires on the volume pots should give you what you want. Ignore the tone controls.
This is the Gretsch diagram

Thx...must be interactive volumes...which I'd like to change.
However looking at your two choices, those both are set up with two volumes and two tones...NO master volume. The Gretsch diagram is what I'm after and after thinking, that's what I probably gave the techs... no matter anyway. The idea with the Gretsch wiring is to get a happy pup blend(with or without the tone) and then the master volume. But no matter how that has been attempted...I get the "Interactive volume" situation you describe. The pots effect each other....rather than like a mixer with a master fader, if that makes sense.

OK...looking again...On your diagrams...I Just take the tone controls out of the circuit, before the switch in your diagram and put the master tone AND volume after the switch...as you've said. I'm learning..
So my question then is... would I have "independent volumes" following the Gretsch diagram? I must have lugs swapped or something.

See the diagram above it's the same as my link. I assume that your tech wired the master volume and tone correctly after the switch so all you need to do is look at the individual volume pots. The wire from the pickup should connect to the middle lug of the pot. one of the outer lugs is grounded and the other connects to the switch.
The output of the switch goes to the master volume pot, note that this is wired differently with the switch wire going to the outer lug and the middle lug connected to the tone pot and then the jack.

Yes...you're correct about your schematic and warrent's link ( being the same) and hopefully what I should have.
I'm beginning to think one of my pup volume controls is damaged or a faulty connection...since different issues now occur now. IOW. ... It started working OK, except one pup volume shut off both in the middle switch position...but then. it just acted like an on/off switch...then " kinda" worked. But the pot always affects the other pup volume too when totally dialed to zero. That always happens
I will check proper pot operation or just replace the pot(s) and go from there.
HUGE thx for all input to date
