The Box Of Doom.. really?

Well, I'll be doomed.

It doesn't seem to matter if it's electric guitars or if it's racing cars, there is always something comes along that is really really crazy. I stumbled on this, it's The Box Of Doom. So do you climb in it, they close the lid and you bash your head against the walls? But, it is in fact an isolation box. Okay, so if you're just tooo dam loud for your band mates they make you get in there with your Marshall stack and Flying V and go crazy. Either way you're doomed. In actual fact the BoD is an illusion. It's nothing more than a fruit box with a speaker in one end and a microphone in the other to which you plug into your amp top.. and go crazy. It even comes in three flavours, the BoD basic, the Pro and the Pro XL. The basic and the ProXL will give you a whole 27db of reduction while the Pro is even less painful with a 29db reduction. The manufactures claim it's.. "The best isolation cabinet you can wish for. Silent, compact and a killer sound." So it kills your sound? I feel well and truly doooomed. So is a box the size of a single speaker going to sound like your Marshall stack cranked to the full a twenty paces? I think it's only going to sound like a speaker in a 12x12 box somehow. For a cool 850 euros without a microphone, I may be crazy but I won't be doomed any time soon (or later).
