hello, my bi chorus 200 seems to go quiet while playing, in both channels. The sound becomes weak and distant and sometimes almost goes altogether. Then the next time it might work fine for a while but always goes eventually. It’s a mid 90’s amp. I think it is powerful amp and I hope I can fix it. Anyone know what could be wrong?
Hello Conor,
From your description of the fault it sounds as though the effect loop sockets are faulty try putting a patch lead between the send and retutn if the sound comes back the jack sockets need replacing.
Kind Regards
