a "portable" sound booth

looks nice...where can i find the plans for something like this?

You could do a lot worse than buy a copy of F. Alton Everest's "Sound Studio Construction ON A BUDGET" (their caps not mine!) ISBN 0-07-021382-8 and have a look at page 52. You could easily waste rather more in unneccessary materials than the $25-30 this will cost you, and there's a lot of other useful information in there as well.

thanks steve.  i'll check this out.
