G & L Tribute L2500: Crackling sound

[Bass Viking]

I played a Tribute L2500 the other day. Nice bass, but when I plugged it in I noticed a crackling noise that became louder when I switched on the pre amp. It wasn't hiss, or the kind of noise you get from a grounding or shielding problem and it was constant, not intermittent. I know it wasn't the cable, and I tried it through more than one amp. I also tried installing a fresh 9 volt battery but that didn't help either. The noise is very noticeable and sounds like sizzling bacon (mmmmm bacon...)

I figure the electronics must be faulty but I'm curious, has anyone else noticed this issue with their Tribute?

Thanks in advance for any help.

Does it make a difference if you're playing or not?

You missed the point. A G&L will run without a battey in it. You need to remove the battery. In schematic of the USA G&L's whenever the jack is plugged in the preamp is on and has the pickup signal supplied to it. Flipping the switch simply pulls the output from the preamp instead of the passive side.

What pulling the battery does is eliminates power therefore the possibility the preamp is feeding back into the signal path. If the noise continues it is a pot or switch issue. If it goes away it is a wonky preamp.

So again remove the battery DO NOT install another and see what happens.

No, no difference.

Spidey, I'm going to try that suggestion for my "wonky" L2K. I've replaced the battery but I'll try removing it to see if it clears up my perma-fuzz situation.
