a MB Bass 400 Plus.

I just bought replacement power tubes for my Mesa Boogie Bass 400 Plus from Lord Valve out in Colorado (whom I highly recommend, btw). During our chat, he mentioned that I should not set the head directly on the cabinet without benefit of some anti-vibration, anti-shock material in between. This sounds like a no-brainer in hindsight, but I'd never thought of it before. I could set the rack off to one side, but I like to set it on top of my 8 x 10 cab for ease of access.

Does anyone have a recommendation on the type of material I should use in between the head and the cab, and where to get it? I've got the 400 mounted in an SKB case along with a power conditioner, tuner, and a BBE processor ... so it's a fairly hefty rig. I don't think the little anti-vibration "feet" they sell at Guitar Center and the like will do the job.

Any suggestions will be much appreciated.

:help:

Don't mean any disrespect but its not complicated. Just find a piece of foam about an inch thick and about the circumference of the bottom of your amp head. Set foam on top of cab, set head on top of foam and voila. If you want to get fancy, you can get "gizmos" that might work, but think about it. All you're trying to do is dampen the cabs vibrations before they reach the head...so foam works just as good, no worse than something more expensive. I've used 1" foam slabs for years with my SVTs and 8x10's and it works great. Get a dark color foam and you will hardly even notice anything is there.

Lord Valve is correct. I use high density closed cell packing foam under my Hi-Watt or I leave it home. It conforms to the cab and head and stays in place. I can't believe we went all those years with only the amp feet to isolate the heads. Stay away from mattress like foam, ie the soft stuff. It tends to compress and get out of the way, it also allows for too much motion side to side and you could have a falling head.

Thanks for your help!

Get a camping ground pad, for putting between the ground and sleeping bag. Any place that sells camping gear has them, including WalMart.

Fabric/sewing store near me has some. Used in furniture too.They also have a variety of densities for other apps. try a Shipping supply depot,or a storage facility. Hoe Depot might have the siding foam used under vinyl siding,but that's prolly too brittle. I've seen some "We Have Boxes" type stores round here, they might be able to help. seek pilgrim!
