Hello everyone! I have a DT50 112 and it has a slight distorted / crackly sound no matter what setting I have it on. I only hear the distorted sound when I am playing. It does not pop or crackle when I am not playing anything. I thought it was the tubes so I replaced them all and it still sounds distorted. Also, I tried another speaker and still heard the distorted / crackly sound so I am sure it is not that. Interesting sidenote... When I plug my guitar directly into the Effect Loop Return, there is no distortion. It's nice and clean sounding. Is it the A25 main board? I like amp and would like to keep it running. Thanks
