"Getting very close to catapulting this thing into the river"

I've been there before... just a different river!

I know you said it's an el-cheapo but before go all medieval on it, there's no shame in taking to a tech or someone more experienced.

I have "cheap" guitars that are real nice players. (in fact most of my guitars may be considered cheap by some)

My point is, don't let pride get in your way and keep you from getting help. If someone else can troubleshoot the problem, you might have a great instrument in your hands.

Also it's easy to get caught up in the problem and unwittingly miss the solution. A fresh pair of eyes is never a bad idea.

Hang in there!

I agree with Mick: get a 2nd pair of eyeballs on it to compare it with the diagram.

WARNING: sometimes diagrams are incorrect, but that's usually with those posted to the Internet. Diagrams provided by the big names along with their products are accurate 99.999999% of the time.

Does it buzz when opened up, but still all connected? I ask because when you stuff the wires in and screw everything together, things sometimes go awry (signal connection tabs touch grounding paint, etc.), and you can have noise, no signal at all, or other weirdness.

Try isolating the problem by testing each pickup as follows:

Disconnect each pickup's hot lead from the circuit, and use some clip leads to connect only the pickup to your amp, one at a time. This will help you determine if a pickup is causing the issue.

If you work on guitars, you need a test lead. Here's how to make one.

Take a 6' length of instrument cable and install a 1/4" plug on one end. On the other end, solder two 6" wires, one to the core and one to the shield. Insulate and seal the connections with heat-shrink tube. On the core wire, solder on a red insulated alligator clip. On the shield wire, install a black insulated alligator clip.

A simpler way to make one is to cut one plug off the end of an old guitar lead and add your wires & clips to it.

Connect the 1/4" plug to your amp's input, and attach the alligator clips to any component in the guitar's circuit you need to test. Remember that you need to isolate the component in question by removing its 'hot' (signal) solder connection from the circuit.

This post has gone on long enough. You need to abandon all of your previous thoughts and start again without any assumptions. Something has been missed and ruled out incorrectly.
This could be any of the following.
Step one: it could be the guitar, the cable, or the amp. Verify that it is the guitar by replacing it with another guitar with the same type of pickups.

Ok here goes.....I resoldered all leads, tested my jacks with another guitar (all good) amp is almost new, And here is the result, it seems the buzz drops completely out when I turn the volume down just a little. go figure... brings me back to a bad pot... Ya think?

"Bad" pots usually crackle or go intermittent or dead rather than hum. You could take the lead from the selector switch to the volume pot, unsolder it at the pot and connect it directly to the jack hot lug. That will bypass the pot.

I want to thank everyone for your input, it appears all the resoldering helped to the point where I feel the buzz is normal "tolerable"

Now I have a second DIY project and better knowledge on "how to" thanks to all of you!

"... to the point where I feel the buzz is normal "tolerable" "

I'm glad you've reach a point of satisfaction, but my experience with Lace Sensors was that they were dead quiet (despite not being true "noiseless").

I first tried them about 6 years ago when we had a house that had "bad" power. Regular single coils were a nightmare, so went to the LS's and the problem was solved. (however, I did also shield the crap out of my guitars)

I'm just saying at some point, when you've put some distance between you and the recent frustration, have another look at this last project and see if you can improve the performance even more.

Maybe this second project will be an opportunity to expand your horizons even further!
Best of luck to you.

You know where to go if you get stuck!

Thanks Mick, the 2ed project came with cheap (china) humbuckers, I will probably replace them.

"But the human brain has a nasty habit of familiarity--it will make a tiny little mistake invisible because you've looked at the thing 100 times. We've all done this more than once, I guarantee. I know I have.

A second set of eyeballs (even someone that knows nothing about electronics) to compare the diagram with the circuit can usually spot the problem right away."

That is oh so true. Over the last 40 years I can't count how many times this has happened.

Sometimes when I'm wiring something up (guitar, amp, control board for a light or power tool, etc.), I get into a quandary and it kicks my arse. And I cannot figure out what the problem is. So I put it down and walk away.

When I come back to it the next day--there's the problem with in front of my beak! How did I MISS that?

It is a strange thing indeed.
