    Default 5150 combo problem.

    Alright, so I'm playing my 5150 combo and I start getting this really shrill squeal coming through the amp with my guitar...it's not really a feedback squeal, but some really high-pitched "hum". So, I jiggle my cord around at the input of the amp and it stops, then I start playing and a few minutes later it starts again until I jiggle the cord around again, and so on. Now, given some of the "pops" I'm getting when I do move my cord I'm led to believe that I have a loose connection at the input jack going into the amp. But, my guitar doesn't ever drop out so I'm not sure if it's a connection problem or not. And it's definitely not a bad cord cause I tried several different ones and the same thing happened. Anyways, have any of you guys experienced this before? I guess I'm obviously going to have to take it to a tech, but the problem is that it's an hour and a half drive to the nearest one. If it's just a connection problem at the jack, I could probably just re-solder it myself.

    Hmmm, tough one. I think hum you describe sounds like you could have a ground problem--if so, re-soldering the input jack wouldn't solve that problem. If you aren't quite sure, I would definitely brave the hour drive and have someone take care of it who knows what they are doing.

    "Squealing" also might indicate a bad tube.

    Nope, these are all brand new tubes.

    bcgvh, do you think you could guess as to how many cycles the hum is? 60? 90? 120? etc.
