why does my bass resonate when not being used.

[amp420]

i have 4 basses and one of them will resonate while in the stand,very annoying!
if i place it in the stand within minutes it starts to resonate and keeps getting louder as time goes on.
i forgot to turn off the amp one day and came home to the house shaking from the bass.lol
my other 3 basses can stay connected with no issues but the fender jazz likes to play itself.
any ideas on how or why it does this?

Is it facing the amp?

Make sure your television is off:

Hey

Is it facing the amp?

Make sure your television is off:

.......and not showing the movie “Poltergeist.” Or “the Ring.”

Wait! Can they come out of flat panels?

Leo speaking to you.....
Seriously it is a resonant sound generated by anything like ac unit, lights, anything that will generate sound or vibrations. I had a fender jazz that would resonate the c note in a church I played. I could play a c, mute the c, & it would keep playing in the sound system. I would have to play another note for it to stop.

no,not facing the amp.
it's an easy fix to turn the volume off but it has me wondering why it does it when none of my others do,i've moved them around as well same thing.

Anyone else thinking it's best to just unplug the bass when not in use...Seems most logical to me..

Any sound vibrates everything to a lesser or greater extent. A sympathetic vibration in your house or outside starts a string vibrating it goes through the amp amp repeats it same note accentuates same string/note. It’s very slow feedback.

Maybe your Jazz is lively. Folks around here might say resonant.

If that’s the situation, people search for those characteristics. Enjoy.

If someone says you will play like Brucepappalardireddingsquireporterleeclaypooljacoclarkeswallowbrownhaslipbachpallidinowhiteprestiavegajohnsonwashington etc. then politely decline and find some other people to hang with.

Haunted. Sell it.

Some basses feed back at lower gain than others. I would expect, if you have several basses, that they'd vary in that resoect.

We are close to exorcist talk here and we can’t say religious! Just kidding!!!

 

[MMiller28]

my amps are on 24/7

Why?

 

[Michedelic]

It's picking up good vibrations.

...my amps are on 24/7,

Is this a Hawaii thing?

 

[Lardass5000]

Yep. They do that.

 

[Phalex]

All it takes is a gain greater than 1.

Turn your amp off, or turn the volume down.

That thing some folks call Mojo, that bass has it!

The one that's resonating is the good one.

A way to think about it, is that acoustic coupling is a two way street. If something is capable of vibrating and making sound, then it's equally capable of vibrating when exposed to the same sound, or at least the same frequencies.

This is quite noticeable on acoustic instruments, but even a seemingly un-acoustic instrument as some acoustic character.

A habit you will learn within a couple of months of owning an active bass ...
(Unless you own a lot of stock in DuraCell or Energizer...)
