"jangly" noise from cab

[Si600]

Last night during band practice I heard a sort of jangly noise from my cab, it appears around a high F (3rd on D) so maybe frequency based.

The cab is a GK MB212, rated at 600 according to the sticker on the back and I run it with the horn switch in the off position. I got if from someone on here, danged if I can remember who, they painted the grill black so if you know who you are speak up!

I'm using a GK MB500 Fusion with the gain on B almost all the way up but the master volumes are nowhere near loud, not even earplug loud last night.

The signal goes through a tuner - GE-7B - ODB-3 - MS70B - Nova Dynamics Compressor

Any idea what may have happened, and is it serious?

I'm assuming that if one of the speakers is breaking then replacement is better sooner rather than later?

Your speaker cab is haunted by the ghost of Jimmy Saville.

If it's not that then I don't know, a jangly noise sounds very strange.

Maybe you've got some Byrds nesting inside....

Does it sound like something loose ? Can you (and a friend, maybe) shake it and see ?

I'd start with loose components too. The front grill is usually a menace - you could remove it completely to check that and if the rattles carry on without it, at least you'l be ready to look for the next loose component inside.

Not familiar with this cab, is it easy to get inside and have a look inside for anything obvious?
