Tone le Bone Posted January 24, 2009 Share Posted January 24, 2009 A loud 'crackling' noise is coming from my amp when I play my Lakland J Bass. This only happens when I play directly above the neck pickup. If I play above the bridge pickup or next to the neck itself, there is no noise. If I press on the poles of the neck pickup with my finger a 'humming' sound emanates, this does not happen on the bridge pickup. Also on removing the bell plate to check the wiring, all seems OK apart from a single black wire which is not attached to anything, just laying loose in the bottom of the routed compartment. Questions: 1) Is my neck pickup knackered? 2) Should the black wire be hooked up, and it is this that is causing the interference? All replies gratefully received.

Delberthot Posted January 24, 2009 Share Posted January 24, 2009 A black wire is normally an earth - is there anywhere on the back of one of the pots with solder but nothing attached? Try playing a note with it plugged in and while the note is ringing, touch the black wire against the back of one of the pots - any one will do. If that solves it then that's your problem.

Crackle free bass again! It was indeed an earth wire that had come unsoldered from the jack plug, thanks again. T le B. Quote Link to comment Share on other sites More sharing options...
