Thanks for your idea about the grill frame being held by velcro. After a little fussing, I got it off and tightened up the exposed screws.
I still have no idea as how to pull out the wooden speaker mounting. I wonder what keeps that in?
The speaker screws themselves are put in from behind, so I still couldn't get at them.
Never the less, when I put it all back together the buzz and the bad frequency vibrato where gone.
So thanks for your guidance and encouragement.
All's well that ends well.
If anyone knows what keeps the wooden speaker mounting in the cabinet, I'd still like to know.
If I do get the problem back, I continue to pursue things with Guitar Centre. I have put an e-mail into the local manager - but no reply yet.
