  2. More screws. Be sure they're going into solid wood.

    Some rubber stand-offs might help, but you'll have to find something rubbery that is the right thickness. Look for some chair leg covers or other such thing and then re-mount the grill with them between the grill and the baffle.

    Put a strip of thin weatherstripping or slice up an old bicycle innertube and line the standoff where the grill mounts and move all the screws over so you're screwing down into fresh wood. Add more rubber standoffs where you can out in the middle of the grill. Rubber plugs you get at Home Depot work well for that. Drill a hole through the middle and screw through them.

    Just an FYI, there's no way you can know your amp is "not even half it's power". The position of the knobs are irrelevant. Too many other variables, including the input signal and eq to determine how much power you're using. Some amps reach "full power" at less than halfway on the dial.

    i add some rubber between wood, screw and grill..still vibrating...the point is that i don't know exactly where the grill is vibrating because the whole grill is vibrating so i don't know where and what to do to stop it..

    Have you tried removing the grill completely - it might be something else? If there's no rattle without the grill just be diligent using plenty of screws and rubber/plastic spacers. Try getting a friend to pluck some notes while you see if you can dampen the rattle by hand - this should show you exactly where you need to fix tightly.

    Yes, i remove grill and then i can play without vibrations... If i hold the grill with one hand in the middle of it and play a open B string there is no vibrations...i will try to fix it with rubber spacers, but i have bad feeling that even tat won't help...but i'll try

    Make sure the speaker is tightened down too

    Cut a piece of 6mm ID rubber hose, like is used for fuel line to fit between the grill and the baffle. Make it just a little bit long so it will compress to the right size. Install it with a long screw though the grill and the hose into the baffle. Choose the location by pressing on the grill whil playing to see where you can stop the rattle. You might need more than one.
