Granite under your amp???

It's probably not really something you want on a rack, the granite will weigh upwards of 200+ pounds. Difference in sound = slight at best. Looks very cool. The best/cheapest way to get a nice one of these is to buy what's called a Machinist's surface plate from one of the online tool vendors. For about $50 you can have a 2-3" thick, polished slab in 12x18 or 18x24" size, slightly more for the larger one. As a bonus, it's a precision flat surface within very close tolerances, so if you need to true up some straightedges or something you are all set. ;-) I've thought of getting a couple, but they are mostly just eyecandy, and at 250lbs, heavy to move around.

I was thinking more like 1" thick. Dimenesions would be no bigger than 17 1/2 x 19 1/2, I can't imagine this coming anywhere near 200 lbs.

A piece that size in 1 1/4" thickness weighs 36lb. I use them for shelves in a sand filled Lovan Sovereign and they work very well.
