Fender active bass buzz

[Muppet]

i have a Fender 18v active circuit in a Dimension bass. I'm getting low background buzz (not hum) which goes away when strings are touched but when pots are touched  (vol, treble, mid, bass) the buzzing increases dramatically.  When I use the Boss Waza headphones (i.e. wireless) no buzz at all and the sound is perfect.  There is no active passive switch.

 

Things I have checked

Batteries

Leads

Amp

Location

Solder joints

Bridge grounding 

Output jack

 

Any other ideas? 

 

Thanks

 

Steve

Get some copper tape and shield the cavity, make sure you link the bridge ground to it. Don't need to buy the expensive stuff, can get 5m off AliExpress for about £3.50 which works fine.

Thanks, that’s now on my list of things to do. It’s only recently started happening though so I’m wondering if there’s a component failure somewhere….
