Sound like it could be an RFI issue.
Could be the amp, cables or the bass.
Consider moving the amp head around and see if the high-pitched sound is affected in any way.
Check the quality of the cables too, making sure they are shielded properly.

Aguilar DB112 + DB112 NT (no tweeter) + GK MB500 (and the bass is a Fender Jazz with Sadowsky pickups).
