    I just purchased an ampeg amp with a 4 x 10 cabinet. I noticed that whenever i am moving around with my bass plugged in it makes a cracking sound. I have purchased a new instrument cable so I know it is not that. I'm not sure if this noise is because of my bass or the amplifier. Have any of you ever had issues like this and could you tell me if it is the bass or the head of the amp.
     
  2. That's usually the instrument cord - from being stepped on too many times.

    Replace it. :)

    You need a new instrument cable. Or possibly a jack repair. But probably the cable.

    do you live in a very dry place??? I've had some static problems with certain carpets and times of the year. You might try an anti static spray for carpets? or humidifier

    Does the cable move at all in the jack?

    I am having the same problem with my amp and it is not the cables because I just bought new bayou cables.

    Well I was kind of stupid one day and... I unplugged my bass with the amp still on and if I touched it some where it kind of made a crackling noise maybe it's not pushed into both jacks properly or something???:eyebrow:

    +1 to replace the cable. If that doesn't work, replace the output jack on the bass, or at least tighten the nuts on it and check for bad solder joints inside the cavity. Worse comes to worse, you have a backup cable in case your main ever does die. That happens way more often than it should. :mad:

    EDIT: Ooops, looks like you already replaced the cable. Wiggle the cable around in the jack. If it moves, tighten the nuts and push the contacts together on the jack. If you can't, replace the jack with a Switchcraft or similar jack.

    OOps on me too! i meant to say he is probably right on about pushing the contacts in on the output jack on your bass. You may have to loosen the nut holding the jack to remove it,its not too hard. I had this happen from yanking my cord by stepping on it a couple of times. Run the cord thru your strap to protect yourself.
     
  12. If you're sure it's not the cable, then static can be the culprit.

    You could try a foot pedal in between the bass and the amp. If the crackling goes away, it probably is static. The high impedance inputs on the amp are sensitive to that.

    If it's not the cable, I'd put money on it being the output jack. Bring ti to a tech and have it replaced, shouldn't cost a lot.

    Was the amp new or used when you got it? Could be the input jack on the amp.

    i had a similar problem with my stingray, it was the input jack. after i got it fixed no more buzzing. :hyper:

    then another bass i have ( ltd viper 104 ) makes a scratchy noise whenever i plug it in. i had it looked at gc and they told me it could be the preamp. since im still under warranty, they'll fix it. :hyper:

    Make sure the pickups are ground to the bridge or remove your pickguard (if you have one).
     
  19. I did. :D

    New cables aren't always "good".

    If you replaced the cable and it still crackles its probably the jack in the bass; replacing these every so often is routine maintenance. Go to the Stewart-MacDonald webpage and order a new Switchcraft jack for about $3.75 and if you can solder, install it yourself, its not very hard. They'll also send you their catalog full of interesting guitar building and maintenance stuff.;)
