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
