New to the site- hoping to find help with a little project.

I do some simple recording at home and thought I might build a guitar amp isolation cabinet. I was wondering if anyone has made one and could provide me with a little advice about how to best go about it. My amp is a Fender Princeton from 1970, so it's not big. I've read about the importance of breaking up standing waves with an irregular construction method, but what would be a good material to line the cabinet with? What would be a good wood? Should I caulk the pieces together? Frankly, any advice would be a good starting point for me. I am in Saint Louis, Missouri- it seems important that I put that down. I only just discovered the site- it looks like a good place to browse about. Thanks, good to meet all of you...

most time, the isocabinets are usually a speaker in a cabinet with a microphone. the cabinets often are heavy to avoid vibration and to reduce the amount of sound escaping. sometimes the walls of the cabinet are lined with sand to increase the mass even more. here's a product to house an existing amp: http://www.vocalbooth.com/products/ampboxes.html check this thread: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=6080

Thanks for the links and the advice- the one with removable panels is the one I'll best try to emulate, so it can be either complete or semi-open. That would allow for various micing techniques. I'll let you know how it goes.
