Amp receives radio station

Unplug your bass. Do you still hear the radio station? The reason I ask is
that my bass used to pick up a radio station. As to why... I don't know. Might
have something to do with the wiring/grounding.

You are right. It does seem to be in the bass. It's a 1973 Fender
Precision.

Call SWR and ask them for a solution - at their expense.
There is no excuse for designing an amp that picks up radio signals today,
with or without an instrument plugged in. We live in an RF soaked world. To
ignore this fact is negligence.

Well, that would work well if SWR were still around. They're caput... I'm
sure Fender's customer service is as good as SWRs (HAR!).

cable. Next time you have this problem, try switching to another, better
cable. You could also have your guitar player plug into your guitar and
cable. If the problem goes away, with his guitar on your amp and cable, it
could be a shielding problem in your bass.
A poorly shielded cable acts as an antenna. The only real difference between
a radio and an amp with a poor cable is, the amp and cable lack a tuner. The
poor cable's length and sections of bad shielding leak RF signals in to the
system, and act as a basic tuner.
Radio Shack, some years ago, sold magnetic chokes. They were mostly used
with microphone cables. The cable would be wrapped around the magnets,
blocking the RF. A new, higher quality cable would be a better choice.
Good luck - George

have your guitar player plug in to your cable and amp.
If the problem went away, it could be your bass shielding. If the problem
continued, with his guitar on your cable and amp, the issue is likely your
cable. - George

I posted this same question a couple of years ago regarding my Ampeg BA112.
New cables didn't help, but somebody offered info on soldering "something" -
can't remember what - "somewhere" inside of the amp.
I sold it on Ebay instead - hopefully to somebody with a less-powerful radio
station in their neighborhood. I replaced that amp with a B-2R and haven't
had any problems since.
I don't know about anybody else, that that scared the living hell outta me
whenever it happened...
Cheers,
Mark

that had very little shielding for the electronics (it was a cheap and heavy
beast at that!)
The amp by itself is going to have a hard time receiving radio signals as
it's prepared to process only the input signal you give it through the 1/4"
instrument cable. I guess it could if it weren't grounded, but I can't back
this up with facts...
Kind Regards,
Nathaniel

Interesting, the instrument it happened to me with was a real Rickenbacker.

cables.

I practice in the living room sometimes.. right next to the TV.
The TV and the VCR have to be off.. or I get scads of static.
I run the output of the stereo headphone jack into a digitech rp7.. and use
headphones..*I can leave the volume up and the speakers working.. that way
anyone else here just hears the music I'm practicing with, at a decent
volume*
Suddenly.. my tone was crap... and I started getting signals from god knows
what.. could have been music, could have been tv.. too distorted to tell.
I replaced the tube in the rp7 and it went away and my tone came back.
How in the hell a bad tube can make the rp7 pickup other signals is beyond
me.. but there you go.

problem which was that whenever I touched the metal corner protectors it
actually made a noise through the amp. I seem to recall being advised that
this latter problem could have been a capacitance problem owing to faulty
mains cable so I put a new length of 3 core flex on - and this did indeed
cure both problem sounds.
Might be worth a try?

I should have said digitech rp7 guitar mulit effects unit.
scuse me.

if not; and if you had disculped the cable; take a look at your electronic
cavity on the bass. Perhaps you could better isolate it with some aluminium
paper; or special paint (don't know the reference; see it in your gear shop;
or in a guitar maker shop)

Man, keep yor amp away from the TV. Those magnets will kill your TV tube.
