Thanks for your input on my noisy grill problem -That is quite a preponderance of bass in your settings and, if by "Preamp 12 o'clock" you mean Gain then, yes, that, with the "master 4 o'clock" would conjure a very significant SPL!! No wonder the grille is oscillating. Looks like trying to get 120 watts out of the 100 watt setting.I would recommend
2. Start with Gain at 9 o'clock and Bass, LoMid, HiMid & Treble at 10, 2, 2, 10. That, for most previous Rumbles at least, is an actual flat setting. Then just tweak slightly to taste, preferably with a Master not over 1 or 2 o'clock. If you use the Overdrive, start with low settings there, as well.![]()
D. Check the screws holding the logo onto the grille. If any of them aren't tight it may allow the logo to rattle, if that's the type of sound you hear.![]()
♤. If the wooden frame of the grille seems to be slapping, then a thin stickie furniture pad, or two, may be needed at the slapping point(s).
Hope this helps.

Actually I had the Master level listed at 4 o’clock when it’s actually set at only 10 o’clock.
Plus the amp is set at the Low Output mode and all voicing modes are off.
I don’t think adding any kid of neoprene tape to the frame is a possibility as the frame is attached with velcro that is installed all the way around, every inch is covered for secure attachment.
Since Fender never responded to Sweetwater they’ve agreed to replace the amp.
Can’t say enough good things about Sweetwater’s response to my problem, Kudos to them!!!
l should be receiving a replacement amp first of the week.
I do appreciate everyone’s replies and hopefully the new amp will work perfectly -
