Jazz bass has no sound! PLEASE HELP!!

[MirandM]

I went ahead and purchased some heavier guage wires, and only red and black lol
Does this chart look proper to you?

yes, looks ok, just replace the blue lines with your red wire.

 

[MirandM]

I definitely take your word for what you’re saying, so if I ask any questions, it’s not out of doubt. It’s just more or less curiosity so I can understand.
I had to buy a new multimeter so when I get home this evening, I will be back at it!

You're welcome to ask anything you want. If I don't know the answer I will say so. No point in pretending.

I'm sorry, I know you don't feel like making jokes, but try taking some sandpaper and sand of the Jazz Bass off the headstock and write ''Precision''- pay attention to spelling! Maybe, but just maybe the problem will go away.

I'm sorry I couldn't resist

Too late! The Glarry decal and its music notes have long been erased. This is my “stamp” if you will lol

I actually just thought about this. I recently purchased an iRig audio interface, and recorded a couple tracks with it. Later on that day is when the bass went silent. I actually thought it was the iRig giving me issues until I went to directly play through my amp, which is when realized it was the bass.
Do you think using this interface could’ve possibly done something?

I touch the probes together and still get a 1…I’m guessing what are you going to say next is that my digital multimeter

Oh no I'd hope not, I miss my RS meter - it's envy! I would never dis what you got: you're trying and learning a lot. Also everyone can't solder so don't beat yourself up you did just fine!

Probes do go bad though and certainly worth a test.

No. Interface failure would not affect the bass.

If pots, jack and pickup leads check out, there's a bad wire/connection somewhere that can kill all signal.

That super lightweight wire many makers use is hard to find defects on - I'd rewire with better quality and heavier stranded gauge - checking continuity along the way.

No what I meant by “you’re gonna tell me it’s bad” is that it has gone bad/defective, and it has…I had to purchase a new one today bc the other wouldn’t give any reads! Ty for the kind words

Thank you sir, I appreciate it! That’s exactly what I’m doing too thanks to the wonderful ppl that have helped me here in this forum

So I owe you a huge debt of gratitude the most most out of everybody else! Mainly because of the list and your professional experience. Earlier this evening and into the morning hours I desoldered everything, and threw the old wiring away. I replaced them with the same guage (18G) wire, but I went with a more robust and stiffer shielding. So here I am with a better wiring setup and fresh solder, BUT most importantly a new found knowledge of soldering electronics, esp concerning pots and output jacks lol

Thank you so much for all the gems you dropped on me, and to everyone else who contributed their veteran bass guitar knowledge of electronic troubleshooting. I’m indebted ty

 

[TastyBass504]

I just wanna give a shout out to all the amazing people that chimed in and shared their wisdom with me, so that I could solve what seemed to me an expert level difficult issue! The success was such a relief. I humbly thank you so much

 

[Matt Liebenau]

I’m glad you got it working again!

 

[MirandM]

great, always nice to know when the result of all advice is positive.

 

[Brian Patterson]

Sounds like the pickups might be the culprit—could be a broken wire or a dead pickup coil. If everything else checks out, testing the pickups directly with a meter might confirm it.

I had a sneaky feeling that was likely, as unlikely as it is, with all the wiring undisturbed. Do you Have another one or two to substitute for circuit testing?

Worse case, this might be a pickup update oportunity! NPD! (New Pickups Day)

I can't wait to hear your successful repair news!

It turned out to be reversed wiring at the output jack, FWIW. And that was a function of a somewhat goofy color choice for some of the ground wires, which lead to confusion with a fairly standard wiring diagram.

In retrospect you were 100% on point

I would have said more, but you were already in good hands and I didn’t think it would actually be all that helpful.

Couple late suggestions for future reference

Wonky readings on ohmmeter can be caused by dead/dying battery...

I had the same sort of symptoms and cured them by wrapping the jack with electical tape so that nothing could possibly touch the shielding. Mine was wired properly, though.

Glad you solved the problem!
