Wolf tone??? Room mode??? Electric bass

Even though the noise is coming through my amp? If this is the case I would be inclined to think there is something to this as I have played in a bands for over 15 years and never had this issue. Only issue is how to fix it.
If you are having this same issue with different amps and different basses, there's literally NO way it's coming from your amp. Can. Not. Be.
 
Huh, I've heard of this happening but never in as many different situations. Any chance your pickups are really close to the strings and just extra sensitive to feedback loops? Are you cranking the active boosts? Just trying to think of what hasn't been suggested yet...

So at practice tonight I took 2 bass guitars with me.
The noise was not as prominent however it did occur, this time on E. I did film it however I don’t know how to upload it on here :/
Interestingly when it happened I switched guitars and low an behold the same thing happened on the E.
I now am pretty sure it’s not the guitars causing the problem. I also have a sans amp pre amp which I switched to which made no difference. I should probably mention that the pedal did not bypass the amplifier so would have still been affected by the amps eq, volume etc.
From advice from Reedt2000 I screwed my pickups in a bit before practice.
Once again the noise sounds like a sustain pedal noise and which continues slightly after the string has been muted.
If anyone has any advice on how to upload videos let me know.
Thanks.

Thanks. Not sure if that’s worked.

If it has then what you’re hearing is the E then an A both notes are played for the same length (muted) yet you can clearly hear the E going on for longer.
I should probably mention that this has not been the worst it has ever been.

Sounds like the snare drum. You can hear the snares rattling like crazy on the E pitch. This is a very common issue. Can happen with any drum, at a variety of pitches.
 
The drummer did switch his snare off. I do know what you mean though.
I know this isn’t probably the best demonstration.
I just noticed your user name and, given the current conversation, it's pretty hilarious :roflmao:

Drum heads are really resonant, does this only happen around the drums? Are drums mic'd up when you play?
 
I was asking for it!
No drums are not mic’d will usually be around the kit tho.
I will try and recreate tomorrow away from the kit.
IMHO, it seems to me like that sound is emanating from a speaker. Can you place a mic close to the
speaker cone, like within an inch or so, this position will significantly reduce picking up room
modes & possibly give us a clearer indication of what's going on.

Depending on the porting frequency of the cabinet (by the way, @Bass Behaviour: are both cabs hooked up?), a lot/most of the sound may come from the port, while there's actually a sharp rolloff in the driver's response where the port contributes most, because the air resonance limits the cone movement precisely in that frequency area. Now, 82-odd Hz is a bit high to reside entirely in the "mostly from the port" region - the cabinet would turn out to be tuned unusually high if so - but should that be the case, close-mic'ing only the cone and not the port* may not show the anomaly clearly.

* [frequencies coming from a port are omnidirectional, because the size of the cabinet itself is small relative to their wavelengths so they make it around it, but a mic placed very close to the cone picks them up several dB's lower than the frequencies radiated from the driver; now, if the port is in the front, the mic can be placed in-between the cone edge and the vent.]

I'd have to go back and re-read every one of the OP's posts to get hip on the detailed troubleshooting process, but a weird interaction between cabs and/or coincidentally similar room modes seem plausible explanations to me.
