I need help , I’m lost (STRING RATTLE)

[FenderB]

Pluck each string then hold the corresponding tuner, you'll find out it it's the tuner or not.

Haha how many of us bass players have OCD?!

No....Not me!

I don't have an Octave Coupler Divider

Are they the same exact brand, model and gage as the previous set? If not, they could have a different tension and your setup would need a tweak.

 

[Greenstreet]

Just about all the bases have been covered here, at least in my experience.
Specifically, I would rule out everything Dwizum and Beej suggested before looking elsewhere.
Same string gauge does not mean same string tension.
If the new strings have less tension than the old ones, it's entirely likely that it's a truss rod issue (you should be doing a setup with string changes anyway).
You should also rock the frets first, just to rule out any fret issues.

 

[Greenstreet]

Even though the OP put on new strings that were the same gauge, string tension can vary a lot from brand to brand. Before trying all these other "fixes," the OP could try loosening the truss rod a quarter turn and see if the buzz goes away.

Loosening a truss rod may make the buzz go away, but it's not necessarily the problem.

For example, if there's a high spot on a fret that's causing the buzz, loosening the truss rod and/or raising the action may make the buzz disappear, but it's not where the problem lies.

Originally, the bass had a high spot on a fret. Now, it has a high spot on a fret, too much relief, and high action.

It's not fixing the problem, it's only disguising it, and creating new problems in the process, problems that weren't there before.

If you think it may be the truss rod, capo the first fret, hold the string down at the fret where the neck meets the body, and measure the action between the top of the eighth fret and the bottom of the string. If it's lower than .3mm, it needs to be loosened. If it's higher than .5mm, it's not what's causing the buzz, and could probably stand to be tightened a little.

That'll make the action higher. I think my fix is the best...forget about it But I'm a serious low action junkie and I hate high action (edited).

I've never been on board with raising the action to hide other issues.

...[a]s long as it's not amplified, that's all I care.

If a bass buzzes in the forest, and it's not coming through the amp... Hmmm...

Fret the E string on the first and last fret. At the middle of the neck, there should be a little space between the string and the fret. About the thickness of a credit card or a little less. If this is not the case, you need a truss rod adjustment. Check this regularly as the space may change with humidity, and or temperature

 

[burgerdj]

Impossible to diagnose without seeing/playing the bass. I would put the old strings back on to verify if they buzz or not - you might have just not noticed, honestly. If you are doing a string change with the exact same strings and getting buzz, you may need a minor truss twist, might have a high fret, etc. let the new ones sit over night and try again in the morning once the neck has stabilized.

Been playing for 30 years. Never heard of "back buzz" until now. Gotta love talkbass. Now excuse me, I have to go check all my basses for back buzz.

Exactly.

I fought with a CV Jazz bass for a couple of years and came here for advice. Someone mentioned backbuzz and that was the problem. I had never heard of it either.
