I bought a new Sqiuer VM Jazzmaster, and found buzzing and crackling after using the tremolo.
I sent it back to the shop.
I received the guitar back yesterday, but the fault was not fixed.
I checked the bridge to jack ground with a multi-meter and it was open circuit.
I made a diagnostic fix by connecting a wire from the jack nut to one of the tremolo screws. (see attached)
The static noise has gone completely.
I found a diagram on the web showing a ground wire to the bridge posts.(attached)
However, I am sure the ground wire is connected to the bridge post
