This is all so confusing.
Some people use Granite, and say it's the best- because marble resonates a high frequency.
Some people use Marble, and say it's better-because garnite resonates a low frequency.
Then you have others claiming solid Maple is the best, because it doesn't resonate, but adds a natural, organic flavor.
Jeeeeeez.....What's the truth? Is there any truth? LOL
BTW, nice amp stand!! Looks marvelous!
