"Weird" electrical issues

I have one bass that recently has started to be quite noisy. It’s the kind of buzz that gets “better” when you touch a metal part with your hands/fingers. It’s most established around one of the control knobs.

This appears to be a grounding issues, I am guessing (but would appreciate a confirmation or rebuttal by the experts here); potentially caused by a bad electrical connection inside the bass!?! (Note: other basses don’t have the same issue; so, not a cable or plug issue).

When I use the same bass with a wireless transmitter, there is no issue!

Another bass has a scratchy volume pot; it’s pretty annoying and it persists both in active and passive setting (push-pull pot). Now, if I use this bass with a wireless transmitter, the potentiometer is silent as the audience in a screening of “Melania”… how can this be? Scratchy when connected by wire, silent (i.e., working as it should be) when connected wirelessly!?!?

Any input is appreciated :grinning_face_with_smiling_eyes:

This part at least is 100% normal and usual. I’ve seen it on many basses

Only thing I can say is check all the grounding internals and usual suspects.

Yes, thanks for confirming. At least, this makes some sense.

The other issue with the scratchy potentiometer is much more vexing…

Electrical contact cleaner is the cheap easy solution.

Thanks. Yes, contact cleaner is an obvious approach, but why is the pot NOT scratchy when I use a wireless signal transduction, and only scratches when a cable is attached?? That’s my main conundrum/headscratcher here… :sweat_smile:

You’re using a cheap wireless transmitter from Temu that filters out the frequencies that the scratches sit in?

No idea.

This could be the answer to that question. The xmitter may not pass the noise that the pot is generating. I would try cleaning it. It is not really a problem if it is not making crazy noises when you’re not turning the pot. But you can also just replace the pot, if it annoys you too much.

Check the polarity of your power source. I would take a look in the control cavity for a strand of wire touching something it shouldn’t. Have you tried other power outlets? Are you using a surge protector?

I enjoyed that movie. Are politics verboten here? I got perma-banned on Talk Bass for disagreeing with mods over the recent death of a “certain” guy.

ETA: I was kidding about the movie. I only go to the movies when forced to go. Lol

Yes.

However making a joke about a box office disaster is not by itself political.

Just so no one gets feathers ruffled it’s good to add some facts:

Total gross box office: $17M

Acquisition cost: $40M

ouch

You can also joke about bribes I think?

Well, I certainly can.

I guess “obsequious bootlicking” doesn’t really have a political bias either, I strongly believe Bezos would do this kind of thing regardless of party in power.

TBH it’s probably the best $23M he’s ever lost

The wonderful thing about bribes / corruption is that it’s done by all sides. Remember this Democrat bozo who got caught with nearly half a million in cash and said it was for ‘emergencies’.

How big is that plumbing bill Bob? Oh it’s gonna be pretty hefty I think?

One of my favourite books (HHGTTG) sums up politics perfectly with one rule.

The Guide states that the Galactic President is chosen by the government, but they wield no real power. Their role is to attract attention, not to lead.

  • The Rule: The Guide explicitly notes that “anyone who is capable of getting themselves made Galactic President should on no account be allowed to do the job”.

That book called so many things right. Series, actually, because the Earth was 100% colonized by the B Ark.

Yes it’s perfectly written

“The Golgafrinchan Ark Fleet Ship B was a way of removing the basically useless citizens from the planet Golgafrincham. A variety of stories were formed about the doom of the planet, such as blowing up, crashing into the sun or being eaten by a mutant star goat. The ship was filled with all the middlemen of Golgafrincham, such as the telephone sanitisers, account executives, hairdressers, tired TV producers, insurance salesmen, personnel officers, security guards, public relations executives, and management consultants.”

I have the original 1978 radio series on my Ipod which gets played on long car journeys.

Yes, but… if memory serves me right (and it’s been at least 20 years since I read the books), I think that later it is revealed how Golgafrincham’s population was suddenly wiped out… likely due to an improperly de-sanitized telephone. :laughing:

Plus the A Ark went in to the sun.

I remember watching a documentary a very long time ago and this guy (Joachim Peiper) came up on the screen. Funny how your brain stores disconnected information.

Twiddle (turn the knob back and forth) many times. Usually works and safer than contact cleaner overspray. I live in SE Asia and humidity requires this be done quite often.
