Buzzing cab handle

[mart]

One of my cabs has an irritating buzz when you play an A note. It's only that note, and there's no clipping on the amp, so I was pretty sure it was a mechanical problem rather than an electrical one. So I started tightening every screw in sight.

In the process of doing this I noticed that the buzzing stopped when the cab was rotated 90 degrees so that the left-side was on the floor. But it buzzed when it was any other way round. So I figured it was probably something rattling in the right-side handle. Sure enough, when I played an A and pushed the handle hard against the cab, the buzzing stopped.

So how do I get rid of the buzz permanently? The handle is a cast piece of steel screwed into a recess in the side of the cab. I've tightened the screws a tiny bit, but they all seem so tight that if I tighten them further I'll probably just strip their threads.

Should I be looking at putting some kind of rubber washer between the screw and the handle? Or is there some clever trick for this sort of situation?

Perhaps try slackening the screws and shoving a little bit of foam rubber between the handle and the cab before doing the screws up again.

i'd take the handle off, get a glue gun and run a thick bead around the mounting and tighten it back up.

Thanks guys!
I'll try the foam first since it's reversible. If that doesn't work, I'll look at the gluing options.

+1 for foam, also silicone sealant is great for these things!

Try Blue tack.

Ok, silicone sealant I can add to my list of non-reversible things to try if the reversible ones don't work.

Blu-tack?!? I like the sound of that.

Thanks again!

I used the double sided sticky foam type stuff you get to attached number plates, that way you can stick it to the handle so none of it is visible when you screw it back into the cab.
