viper picking up radio !!??

[slate]

hey y'all ,
my viper is picking up radio signals at high volume .
i've eliminated everything else in my chain - out of 12 guitars only the viper does this .
its obviously the electronics at fault somewhere - anybody know where to start ?

you sure it's the guitar and not your amp?

Check the earths in your guitar with a multimeter and check whether and how the shielding is connected (the black paint in your cavities is shielding paint and should be earthed) :) Try using a different (and different length) instrument cable, too. I really do expect it's an earthing problem that can be fixed with a bit of re-soldering of joints, but worst comes to worst you can solder a cap across the jack and bleed radio frequencies to earth.

you got emgs? this happened at practise on a few occassions with my guitars with emgs...i was picking up german radio station lol!

yes ive got emg's - got em in other guitars too but they dont pick up the radio .
it is more apparent with my monster cables than with others that i have (george l's / cordial) , but i like the monsters... and its definitely the viper , not the amp .

I've only had this happen to me out of my amp, the next door neighbor has some huge ass anttena he uses for communicating to some guy down the street. I don't know if he knows the telephone exists.

Definitely sounds like it's an earthing problem causing your guitar (and instrument cable) to act like an antenna. If you have a multimeter you should check the earths in your guitar (especially the wire going to the jack). If you don't have one, you can still check visually. It might be a dry solder joint or something else that isn't visible to the naked eye, but it can't hurt to have a look.

You can do some simple checks by plugging the guitar into the amp, and carefully using a length of wire to connect earthed points (the back of pots etc) directly to the earthed part of the output jack. If you hear a change in the interference, you can confirm that the section of wiring you're bypassing is faulty and the cause of the problem. **You're only dealing with 9 volts here, but still be careful, it's always better safe than sorry.

:confused:

[Fikealox]

Why are you confused?

[Kgry]

WTF is earthing? Do you mean grounding?

[slate]

yes , he does - its the same thing .

heres a link to a photo of the wiring - looks weird to me ( nothing like an EMG schematic ) , although this is how it came from the ESP factory...

think i might strip it all out and rewire it as the EMG diagram .

It's a bit hard to see what's going on with the wiring in the photo, but I think rewiring it is a good idea and will probably solve your problem one way or another. Good luck and let us know how it goes :)
