bark board? any other really stupid questions....

[JazzMasterWil]

I'm having pretty good result recording my guitar through a pod for most of my recordings.... but on some of the more bluesy stuff I'm just dying to mic up a cab.....

My room sounds awful, so I thinking about making a little iso box.... I had a pretty good idea for one and bear with my here, my paintbrush skills aren't what they used to be...

The 2 layers of black are thick plywood. The yellow inbetween the plywood is sand. And the green on the very inside of the box is bark board.

I don't actually know the proper name for "bark board". But I can describe it... If you've ever driven past a house building built and you see a lot of black boards all over the place, that black board is "bark board". It's basically made of bark and sawdust and then coated with tar, it's insanely cheap, and I have access to a lot of it.

Bark board can be a little fragile, so I was planning on covering it up with some kind of real cheapo frabic before I put it in the box.

The basic plan is to built the box using strong screws and to chaulk everything up really nicely.... I want to rig the lid up so it can open like a door and latch back shut.

The iso box will be designed to house a 1 x 12" speaker cabinet and I think it should have completely dead walls. I don't think much sound will reflect off something a flimsy as bark board.

And if the bark board vibrates the the vibrations would go to the plywood and the plywood would have several pounds of sand behind it.... I think it'd take a whole lot of volume to get sand to vibrate much....

Let me know what you guys think about this? I based to idea off of this iso box. (See link below) But, I'm trying to make a box of that qualitity with readily available materials.
