I am Mark W Shoemaker, owner of A440CPS and I would not believe everything you see online inlcuding the previous review, especially if anonmous! I supply several hundred events in the northeast USA per year. Besides Mr. Joe Clark of Crocodile Rock in Allentown who paid a $6500 judgement to settle a $1200 rental there is no one else that has anything bad to say about me. Everyone knows of Joe Clarks character! I am the best at what I do, 1 million invested in new gear and my personal attention to detail on every concert I service. So, I imagine the last review was Joe... Thanks, Joe I would like to share my experience with Joe Clark... everyone needs to know before dealing with a person like him!
