pickup crackling

[fiel]

Hi, I have here for repair a nice Martin Guitar with a LR Ibeam pickup.
this works very well with the exception of an loud crackling from the Pick up from time to time. This crackiling can happen after 5 minutes of after 5 hours. This happens also without any movement of the guitar.

Any idea what the reason could be ?

Best regards

Is the crackle accompanied by a pronounced and bassy pop-pop or does it more closely resemble the sound of wind on a microphone?

Hi Bryan,
It's a bassy pop-pop sound, as if something is breaking...

[Bryan McManus]

An intermittent bassy pop-pop sound is often a poor connection between the power connector and the battery terminals, though it would normally be induced by movement.

As a test, pull the battery from its pouch and, with the guitar plugged in and the amplifier at a lower volume, wiggle and mildly twist the batter wire snap's connection to the battery. If you can reproduce the pop-pop simply by pushing down on or slightly moving the terminal snap, the one that fits onto the battery's small(positive) terminal should be crimped tighter.

This was more likely to occur with the blue and white battery snaps than with newer ones that are all black.

Please let me know if that is not the issue.

I have this problem with my gigpro- crackling induced by movement. Any other things to try?

dakota,
Is the crackling started with movement in general, moving the cables, or something else?
