This does seem to be a downside of tubes. I've noticed a few times the tubes(?) seem to act like little antenna. Even picked up radio stations in some locations.

My technical explanation is the same as to why tube amps are louder. The sound gets in the tubes and reverberates around and amplifies the sound, or the interference in this case. I'm sure you and Miles have a different way of explaining this!*

*This is not to be taken seriously.
maybe not to be taken seriously but not really far from the truth...see? contrary to popular belief...bass players CAN be smart...
 
Thanks for the help! :thumbsup:

Still looking into it, was less late last night, than in the afternoon - but still noticeable.

I just got it out of its case yesterday, after about a 3-week "rest". Same strings (DR neon reds), same settings (v1=10, v2=~7.5, t=~8), but I did check both. Checked w/ 2 cables, & when that didn't change anything, I tried a couple of other basses (even a non-Thunderbird :jawdrop: ).

It does seem to be environmental, I can move the VP around in different places/positions & the hum gets less/worse. Lowering volume, especially on v1/neck pickup makes a difference (obviously), and using either overdrive makes it more noticeable.

But none of my other basses are doing this, and this one wasn't doing it previously.


Guess I just wanted to check if it was a feature, before I started looking for bugs ;)
Ground wire to bridge got disconnected?
 
I've done some more experimenting, and found two things:


1) Whatever it is, it seems to be in the ceiling over my "practice area" (aka, living room....:unsure: ). No overhead lighting, but may have been at one time - maybe wiring still up there? But seems to be the only area, so far, that causes this.

B) Out of the four Thunderbirds I've tested so far (Vintage Pro, Pro 5, Blackbird, Classic Pro), the Pro 5 is the only other to pick up the hum, and it's not as loud/strong as with the VP.



Guess my solutions for now are:

A) Sit in a different spot while playing, at least with the VP. :facepalm:

2) Ignore the noise/pretend it's a custom distortion effect. :thumbsup:

n) Play a different bass. :(

n+1) Get the owner/manager to figure out what it is & fix it....:roflmao::roflmao::roflmao: - yeah, that's probably not a real option :meh:

All the best solutions always involve fire and explosions...

Any fluorescent lighting in that space? Unusual lighting or dimmer switches?

No, nothing but empty ceiling, in the middle of the room.
I did find one other spot in the living room ceiling (out of the places my cable would reach), at the edge near the closet, that has the same effect. Nothing there either :thumbsdown:

I'm thinking it's got to be some leftover wiring or junctions or some such, from previous lighting setups.


I hope :nailbiting:

It is the back hair that gives good insulation allowing mature Canadian men and women to survive cold winter nights...

Disregard what sounded likely like a catty comment. In quickly reading I thought you were jokingly implying both were endowed with plenteous follicles. After reading it again, my reply was not humorous.

Very good point about dimmers. I think about fluorescent lights but rarely think of switches.

A local sound guy who had a company that installed sound systems once told me he had trouble with a church once that was hard to figure out. They had trouble on Sunday's, but when he would come to check things out he never could find the hum in the system. One Sunday it dawned on someone in the church what the problem was coming from. It was quiet for a while early on, then started making noise. They figured out that someone came into a restroom downstairs. They isolated and determined it was an exhaust fan downstairs in a restroom.

actually, N+1 is the proper mathematical explanation for the need of another Thunderbird. N being the number of birds you currently own now.

1) try a different outlet for the amp.....
2) with the setup making the noise, start turning off breakers till the sound stops with the setup obviously still on....if one of the breakers turning off quashes it, it should point you in the right direction....:thumbsup:

Cute! But the reality is that hot tubes attract stranded Venusians (who average 3cm tall). Desperate for news from home, they build radio receivers into whatever they live in. Since they can’t hear or sense anything below 60khz, they have no idea of the signals they are injecting into the amp. Under a treaty we signed with the Jovians, we can’t tell the Venusians about this. No one knows why, but since the Jovians (not Mike Matthews) control the tube market, we don’t argue.
