Easy solution for the resonating, vibrations, etc...cut a yoga mat to fit under the amp and double or even triple it up, and this will stop most of the vibrations and if you cut it close, is almost undetectable. Also helps save tubes if you play loud , stops some vibration to them as well. I have tried a few things with my bass rig and the best thing so far has been a restaurant style rubber floor mat...the ones with the holes absorbs some shock when placed between my rack head and cabs below...anybody else have ideas...always willing to learn new tricks.
