I am losing signal in my rig & need help find the culprit. Bass > pedals all in series, no loopers > amp. The sound is fine & constant, and all of a sudden the volume decreases more & more, then I have nothing. I can pull my instrument cable from my board & go straight to the amp & it works fine. Finish the song, go back to pedalboard & it is fine for a while. Then.... it will happen again. I can find no rhyme or reason as to when the signal goes, or as to anything that might be causing it. I am using a Visual Sound One Spot power supply. It makes me think the problem is coming with my power, because the signal fades & goes away. Usually, with cable problems they either work - or they don't. Intermittent problems can be detected by wiggling cables around. But, why does it come back & work fine after I replug? I don't turn my power supply off, I don't unplug anythign except the cables going into my pedalboard. Ideas? And, FYI, this is one of those problems that you can't make happen... like when you car is doing that 'thing' but, you can't get it to do that 'thing' when you take it to the mechanic.
