Anyone have a hiss in their towers when they turn them downto zero on the ws420. mine seem to hiss. i usually only turn them on when we have a rider. or hanging out swimming.

I was doing and inboat test that david from Earmark recommended for the bass boost button vs the sub eq output and finally got that straight,( thanks David went with your advise.) but i noticed the tower hiss.

I had to retune because my one year old likes to turn the knobs when she is driving??? she can't reach the moomba steering wheel hub yet
