So I’ve had this issue since the completion of the build and it’s really “driving” me crazy, pretty much to the point were I stopped using the high gain side of the pedal which sucks because I like that sound as much as I like the low gain side. I’ll do my best to describe it. There is an almost static crackle broken speaker nasty overtone that happens when I really dig into the strings while on the high gain side of the Duocast only in 18v mode. I’ve turned down the trim gain lvl and it helps and when I roll my strat volume knob down to 8 or less it goes away completely but I really want to utilize the amazing sound of my volume at ten without having that overtone crackling occurring. Does anyone know what it could be? Maybe a bad transistor? But it sounds amazing at all the other settings. I also have heard this strange crackle static on the Coda Black hole build I did but it’s no where as prominent as my Duocast. Any thoughts would be highly appreciated. I have tried to record this noise and just can’t seem to capture it. It’s some what random but too often at the same time. HELP. I used all the build doc parts even paying up for the OC71.
