    I recently bought a new bass (Jackson Concert) and I am very happy with my purchase, but I keep getting this feedback and the only way I know of to stop it is to put my finger on the volume and tone knobs. Is there an easier way to stop this feedback, I can only hear it when I turn my amp up. I dont get this feedback with my fender so im not really sure what its coming from. can anyone help me prevent this feedback?

    Thank You
     
  2. This sounds like your bass is not properly grounded, or shielded.

    Hmmmm....

    New bass, but it could be the pick ups have some lose windings and they cause such problems - though it is more like the bass screaming not typical feedback?!?

    The cure for this can be "hot wax dip"!!! Sounds horrible, but is really effective way.

    Hope this helps,

    Feedback is a loop where a noise gets very loud within milliseconds and is a high pitched, painful squeal.

    If you're able to stop the noise your bass is making by touching metal parts on the bass, I believe that what you're describing is hum, not feedback.

    If it is indeed hum, Mesa Man is on the right track.

    Your bass is either not shielded properly or is not grounded.

    OK. so it huuuuummmmmmmssssss!

    Normally there should be some grounding wire(s) from the plug ground to the bridge. If this is become lose or the soldering is gone or done bad (it happens bro! - some cold solder joints look good but they sure don't work properly for electricity). Also one very efficient point is shielding the cavities of the pick ups and there are some usefull stuff on Lane Poor's pages (www.lanepoor.com) plus the "hot wax dip" (also described at Lane Poor).
    Keep on browsing and eyes wide shut open!

    Am I confusing fellow bassists here!!!!

    Hope this gets you to right tracks,

    I just found out that when I use my Nady wireless system I dont Get any hum. So would that mean that my cables are just junk?
     
  8. Might be, or the wireless has got something to cancel hum. Try other cables to find out. Good Luck!
