Anyone else have this problem? How do you combat it? Certain frequencies sometimes make the top of the amp rattle and when I exert weight onto it the rattling goes away. Sometimes I've used a tuner in the past or some type of weighted object to avoid it but I don't want to find any more loopholes in the system :hmm: I have my Boogie in a rack and I want to put a rack tuner in there so that may be a problem considering that I won't be able to put any weight on the top of the amp. Any suggestions? I can use like piece of foam but that'd be dumb considering I have a rack. I could also just run the amp off the floor with long speaker cables but i would not like that option either. Any suggestions? I'll post pics later so you can see my rig :) P.S this does not have too relate strictly to the 400+. Perhaps there are SVT2 or other metal bodied amps that have this problem as well.

I've got both of those amps and neither one ever rattles.

Assuming you've got all the top covers (and side-chassis/bottom-cover) mounting screws snugly instaled, the easiest solution would be to simply wedge a piece of dense foam or hard-rubber between your amps top cover and rack case or use a much thinner piece between the amps top and the rack tuner.

As your pressing down on the amps top cover to stop the rattle, your also exerting pressure on each of the sides, so the top cover itself may not necessarily be the rattle culprit, the true cause may possibly be something else loose below...
