Recommendations for custom amp stands?

Nice work bigtwin!

I'm lost as to why some of you think the material the box is constructed of will make any difference at all? It strictly contains the sand! Perhaps the material the top plate (sub plate) the amp sits on is made from will have some unique tonal qualities but  I think the sand will diminish any tonal differences beyond recognition. 

There are materials for the casing to contain the sand that can offer a very attractive effect on how local kinetic energy is dissopated / sampled. 

Using such a material in conjuntion with multiple grains as a filler, will be an upgrade to a more common design.

Successfully tidying up an End Sound will create a condition where Tonal differences are much easier to discern.

This is different to using a material to influence a particular tonality. 

+1 on Timbernation.  Beautiful woodwork, gets them off of the floor, solid wood.

So where can i get some of that Panzerholz, Delignit or similar in the USA (ideally in Florida).  I dont need a whole 4x8 board.

@robbiesd  I agree with you.  With the design I used, the top panel is floating and completely independent for the box carcass.  This is key, as only the floating top provides a break in the vibration chain as it were.
