Sign in to disble this ad
Hi all.
I am testing my new Cort action.
very satisfied.
At first I thought that the j-pickup hum was a problem until I found some topics explaining that's it's ok for them to hum due to their features.
But except the hum I can hear a very strange kind of noise.
it's like hearing a very short sound like saying "chick"!
sorry for my english but I wish I could describe that noise!
I can hear that noise 1 time every 10 seconds with the amp quite loud.
Oh! it's just like hearing the dust on your old vinyl-disc player playing an old disc!
that's 100% the same
(That's not a grounding problem.Sure about that)

Try facing a different direction and see if it changes...probably should try shielding the control cavity with copper foil.

~Stan | thanks stand
1.How would you call that kind of noise? (the same noise you hear from the dust of old vinyl discs)
2.Why I have that kind of problem only from the j-pickup then?
3. RF? What's that?  |

Stupid question to get out of the way: does your pickup have exposed pole pieces? It could just be your strings hitting the pickup. |

Never tried another cable.
but note that I hear that click noise ONLY from j-pickup
do you think that it has to do with the hum that the j-pickup does? |

As said above, shield it. You'll need this sort of stuff. |

There is a p-pickup
it's the p-j cort action bass.
but then again why I can hear that noise (not the hum) only from the j-pickup?
How would you call that noise?
-Oh! I have that bass for only 1 week, I shouldn't take the risk and shield it  |

Shielding would be your cheapest fix.

I thought that only hum is predictable from j-pickups.
I think that I will try and risk the shielding project in the future.
Do you think that the tape is much better than the copper paint I saw on the site? |

You could also try contacting the place that you bought the bass and have it checked out to make sure that it is not an electrical/grounding problem.

or not? |

~Stan | can you take it back to the shop you bought it from and tell them to fix it? i would not accept a 1 week old bass having problems.
