Bought this Amp used for fun and to just try something new. Had no issues with it up until recently I noticed the loose Amp input jack. During rehearsal last night I noticed my signal cut out multiple times and I had to jiggle the 1/4" cable around until the sound came back. Sometimes the sound would get wonky and warbly at times. I attached a video for reference. My questions are: is this something I can just tighten myself at home and not worry about it anymore? Also, could the loose amp input jack cause some of the wonky/warbly noise i heard at higher rehearsal level volumes? I don't think I've heard those noises when I'm practicing in my room at lower volumes.
