High pitch whistle

[Bassist on the Run]

Evening all. 
so I’ve recently purchased a couple of basses a spector rebop 4 and a 5 also a Warwick fna jazzman. 
 

im getting a high pitched whistle when I use certain pots to change tone etc 

 

I’ve gone from amp to audio interface to see if it’s amp issue and it’s the same across the board. I’ve even turned down the pre amps to see if this helps. 
 

any ideas would be most appreciated

the chance of two basses having the same fault is low. 

Have you tried a different cable? (this could be the simplest common denominator) 

Have you tested it all in a different room/building? 

and Doing what, to which pots cause the sound?

And, new batteries in the basses?

What I’ll do is send a little vid once I’ve done my days slaving at work. I hear your point same issues leads are different and battery’s are all new.

Is this wireless? My bongo can't be used on a 2.4ghz wireless directly plugged in without getting a high pitched wine, but can if you connect it via a short wire.

Either that or some sort of electrical inteference in the house, TV / Wifi etc.

Seems to be an electrical problem. The bass sounds fine and if I move away from the area the high pitch get quiet and disappears if I move slightly it’s back. I turned all my electronics off one by one and nothing eliminated it. I’m thinking it could be something wrong with the plug in that area.
