Warwick WCA 410 problems

[Kordly]

Hey.
Bass cabinet Warwick wca 410
From the rear of the cabinet is a whiz-noise when playing the 4-5 string and when a lot of bass. May be of jacks or data tables.

Use only one month previously had no problems.

What to do?

 

[shaftbass]

There's not much back there except the rear control plate where the jacks are mounted, and the HF horn adjuster are. Maybe something is loose. Perhaps one of the jacks or the plate itself?

You could play while you are behind it, and then touch things to see if the vibration stops.

 

[verb]

It could be an air leak from a panel joint or around the control plate.
