We ordered the flexible Faraday pouch for our P-SB7 spirit box and it should be here in a couple of days. We will let you know our results with it once we run it through its paces. This flexible pouch specifically shields your P-SB7 from receiving AM / FM music and talk radio signals. By positioning the P-SB7 at different locations within the Faraday cage pouch, you can block ALL or portions of strong AM/FM channels. The pouch is big enough to hold a P-SB7 and an amplified speaker as large as an Altec Lansing, like the one Zak uses on Ghost Adventures. According to the manufacturer, "this accessory is perfect for the serious Spirit Box user because it will allow them to experiment by attenuating and 'tweaking' the radio frequency reception during their sessions."
