Ok, so I took my Microcube and my Epi SG up the street to do some busking yesterday. I plug it in, and the signal keeps cutting out, Tried looping the cord through the strap, still cutting out. Went back home and tried it again, same cord, couldn't get it to fail. So I tried busking again today with another cord. Again, outside, the signal kept cutting out. When I wiggled the plug in the guitar, the signal was in and out, and crackling like crazy. Ok, I thought, it must be the input jack on the guitar. Just got home and tried it again. Again, it works perfectly and will not fail no matter how much I wiggle the cord around. I'm either losing my mind or missing something really obvious, I guess. Any ideas?
