Okay this is really strange. I have a Walter Woods High Power Stereo amp. Last night during a live recording at my chruch I had no sound. We played the first 2 songs and when we started the third I had no sound. When I turned off the amp, it never completely powered off. After I unplugged it I was able to get a sound (not a good one but a sound none the less). There were a couple of new situations here. I was using a used Tube Works direct box for the first time. I plugged into the box and then ran it into the Woods. Also it was being ran through a sound system with people who did not know they were doing. Other than that I have used the same set up for the last year and a half. Could this have been caused by the direct box? I did not get my true sound until I disconected the box and reset the Woods for the second time.
