When I turn my guitar amp on, the radio plays through it.
Its just about the most annoying thing ever.
When I stand in certain spots in my room it will stop.
How can I keep it from doing this?
And “go stand in that certain spot” is not a solution to my problem.
EDIT: I forgot to mention, its a pretty old amp and I bought it used. But i hadnt had this type of problem since about a month ago.
lmao… your guitar is acting as an antenna… simple. ive heard stories of guys having that hapen before, your cables and stuff probably arent sheilded enough, what are you using for a guitar also? that might be key, and lmao… awesome segmant from Spinal Tap… W00t, the radio playing through his wireless setup, lmao, anyway, i’d just say sheild stuff, or stand in that certain place
500th post btw w00t
yes a shielded cable will help you no end
If I were you I would buy a new amp and keep that one for when you want to play your radio very loud 
I’m not sure what causes it, but it’s happened to me a couple times before. With a guitar amp and 2 sets of computer speakers. They were all pretty old…
Hmmm i dont know if this could be the same thing but…
Sometimes when im talking on the phone to someone and i get to near to my alarm clock while its on i hear the radio in the phone. same problem maybe?
No. If you were me, you would be dead broke.
How much could i get about a 15 foot shielded cable for?
15 foot? easy 15-25 bucks.
check at a local guitar shop, you can probably get a cheap one for like $15-$30 or so, There are some better ones, like fender makes some odduns, liek super male 1/4 inputs on the ends, odd, but they work i guess, i dont like the fender amp cables though, i stick my cheapy ones from a local guitar shop, just any newer cable should do it, if it doesnt then, you might have to sheild some wiring inside the amp itself, which would be a little bit, ALL i think it is though is your cables,
by the way, how old are you amp cables? and whats the year/model/make of the amp?

OK: think it through logically. If you stand in some spots and the radio sound disappears, then it would suggest that the amp is not the cause…breathe sigh of relief. So: guitar or cable. You could rig up a shield with some kitchen foil wrapped around the cable, and an earth connection. Only do this if you know what you are doing electrically. If you have no idea at all get someone to advise you on safety issues, and check you are correctly connecting it all up. (Here endeth the disclaimer). If the radio pick up goes away, then it would seem likely that the cable, rather than the guitar is the cause. Try different length cables, borrow one from a friend. If the cable or the guitar is the sole cause, you might expect to find the same problem with another amp.
Also try moving the amp, or even just rotating it, and see if you solve the problem. ( it could be a combinational problem requiring both your amp and your other components to be in circuit.)

What’s happening is your cable isn’t shielded. Insturment cables are unbalanced. Meaning, the positive, negitive and ground do not have their own connectors. If I remember correctly, the negitive and ground share the same signal and therefore is able to pick up radio static. You’re going to want to shield that cable. You can make your own with a soldering iron, cables and connectors. I’d have to look up on how to do it as I haven’t done it in 2 years. But it’s not the amp, it’s the cable. I’ll have to look up the answer in my audio books to be sure, but that’s the problem.
Unibikeling, for all of our sake, no mor lol/ lamo/ rotf/ rotflamo.
A lot of peoples have this problem… When i worked on a Luthier/CUstom STore… a lot of peoples asked me why that happens…
First thing to check is your cables… If they are ok, check the eletric part of your guitar… A cool tip is make a Faraday Cage with a cooper or a contuctible material… (Luthier Store where i bought my Shielding material).
After that, if the noise don’t stop, try to use a decent line filter… That happened with my friend… The energy of his house was “noising” his amplifier…
Some places close to antennas are worse to play… Your amplifier can be the problem to… If it isn’t shielded on the right way… you can have a lot of noise!
There a lot of myths about shielding and noises in the guitar sound… Google it and you will se that is a very popular problem!
Bye!

These are cool problems. A guitar amplifier should only amplify audio signals. To amplify a radio transmission it must first detect the audio envelope that modulates the RF and then amplify that signal. There is no detector (ideally) in the amplifier or the cables. Possible detectors are in the guitar pickup (if it is piezoelectric) and in one of the amplifier stages because they have diode semiconductor junctions or diode-like behavior in some of the vacuum tubes. No matter which one and I don’t know if the amp is solid state or tube or hybrid.
The cable may or may not be the antenna, it could just as well be you. You could also be the variable capacitor in a tuned circuit formed in conjunction with the inductance of the cable which varies with it’s shape. Sorting out a problem like this can be a real pain. Certainly the recommendations to shield the cable are good ones. Other approaches are to systematically earth ground different parts of the problem. As Naomi mentioned, you must consider safety when grounding yourself and operating electrical equipment with unknown grounds.
Ground loop chasing is a real art. Proper shielding techniques are also a real art.
Oh my, Gregory. You were on such a roll.

Be still my heart. Would you like to come over and see my collection of MOSFETs sometime?
Harper, you work with DIY Pedals and amps stuff too?
I make pedals 
I have a nicea collection of Mosfets, BBD’s and all this stuff
Bye!
No. I work with ions…and boneheads.
