why does my bass resonate when not being used.

any ideas on how or why it does this?

Residual energy left over from the big bang

FWIW, I've got one of those cheap $50 B1ON effects boxes (my only pedal). Primarily I use it as a tuner, but my one effect I have on constantly is a noise gate that silences output under a certain overall level, so when I'm playing it's out of the way and doesn't affect the signal, but when I set the bass down for breaks etc it does it's job. Prevents resonance by doing so too. Just a thought.

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.

Yes! What Mr. Deck said.

Consider yourself fortunate to have such a “live” instrument. :hyper:
 
not being tubers I figure there's less potential problems than if I turned them off / on all the time
Your amps were not designed to be left on 24/7, but they were definitely designed to be turned on and off frequently. Keeping them plugged in and powered on 24/7 also greatly increases the chance for damage from things like power surges and brownouts.
 
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?
I think you have discovered the worlds first verifiable free energy device.....:smug:
 
All kidding aside, it sounds like a classic case of sympathetic vibration. Hollow body instruments react readily to this and are prone to feedback, causing some people to stuff the F holes with foam to quiet them down. I remember reading how there was a test done with acoustic guitars decades back where two groups of identical instruments were separated. One placed in a quiet environment, the other subjected to music 24 hours a day for however long the test lasted. The guitars that had been surrounded by music were later judged to sound better than the other group. Who knows why?

I have a Gibson Les Paul and Marshall JCM 900 100 watt head going through 2 4x12 cabinets. I turn it up to full volume, set the gain all the way up, leave my Les Paul plugged in on the stand, then go to work. When I get home, I walk through the door to deafening feedback coming from the amp. My guitar seems to make sound when it's not being used. Should I take it in for repair?
