Weeping demon wah, if you’ve ever had or played one of these, you know how versatile and sought after these are. The input needs a new nut, i tried to replace it but it doesn’t work the best. It doesn’t grip the threads like it should…so it doesn’t connect 100% with a guitar cable. But it does work. I took off the backplate, made sure everything was connected and it works. Uses 9 volt or plug it into your pedal board.
