Hi everyone! I just built a Chrome Dome distortion, but having an issue. It works mostly, but somehow when I change the tone knob, it cuts the volume and sounds quite dull in the middle and if I turns it back and forth a bit, then the volume comes back and it sounds normal again. I already checked the tone knob and other components multiple times but couldn't figure out. If anyone can help, it will be really appreciated. Thank you guys!
