New Ampeg BA-115 v2 - noise

[R2Bass]

Nice tone by the way and how far is the treble turned up?

It is at 6/7

 

[Bass'd on a true story]

A ton of new combos have this issue. It's especially prevalent in the low-end Ampegs and Fender Rumble 25s (specifically 25s). It doesn't seem to be a problem that progresses to be worse and I have no idea what causes it.

I haven't heard that type of noise from the units I played in the store? but I haven't played one in my home and I think it bothers you enough to get it at least get it looked at that way you know that's what I would do.
