I purchased a used Para-Baby off eBay and it arrived w/no power supply other than the internal 9v battery. Knowing that makes me the worst kind of customer a business in these depressed times could possibly have.........I contacted Chicago Iron w/a great deal of angst about whether they would answer my "power" questions. Within hours of my emai to their site, Kurt Stier responded and answered all my questions. We then had a multi-email correspondence about effects rigs which was extremely cool. He is just finishing an exact replica setup exactly like David Gilmour's "Pulse" tour rig. I sent him pics of my Geezer bass. He turned me on to some really interesting info about all of the new stuff he just sent Geezer for his '09 tour! What an incredible asset to the music and bass playing community and an overall really nice guy!!!! Patronize Chicago Iron because merchants like Kurt Stier deserve your business and work hard to get it. He could have ignored me, but he didn't!!!!!
