Electric Mistress Flanger

Tomorrow i'm going away for a few weeks, so I wanted to complete a fun build today - the Electric Mistress Flanger. It's a great sounding flanger, built on home-etched PCB. The original uses 18 volt and a SAD1024 chip that is hard to find / expensive. The layout I used (made by jorge r @ diystompboxes forum) is adapted for 9v and uses a common MN3007 chip insted. Original thread here. A recommended and fun build!
