Played a gig last night on a raised hollow wooden stage. I had to cut all my lows out just to get a sound that didn't sound like swamp gas bubbling up through primordial mud. This got me thinking about this Amp Isolation Platforms by Auralex. Being a DIYer and not really wanting to pay $50 for something I can probably build out of scrap wood in the basement, I thought I'd ask if anyone on TB had any experience with building something like this. It just looks like a piece of wood supported by some dense foam. Or do you have any experience with the Auralex product. Does it help?
