There's a guy in my town that designed this wooden thing that doubles as a slant stand for a open back 2x12 combo and has like this huge wide port on the bottom of it (almost like a huge horn) that gives the amp this 3d type sound and gives it more bass. He wont build me one or let me see the plans or the inside of it. I WANT ONE!! Anyone ever see something like that? I wish I had a pic but I dont.
