Hey guys! Haven't been around in a while. I just built a morning glory based on the tagboard fx layout. I built it for a friend and really need to get it working soon. So it works perfectly for almost 2 seconds when as soon as I plug in power and then it sounds like someone is turning the volume down until it's off. It just dies. I've tried replacing the ic and the transistor because I have both socketed. It does somewhat work with one particular 4558 ic, but with anything other than very light picking of the strings and it sounds terrible. And the voltages on the 4558 ic are way different than with the correct ic. Just wondering if anyone has had something like this happen before and if anyone might have any clues to the problem. Maybe I've just gotten rusty at building pedals lol. Any help with this would be greatly appreciated!
