Hartke LH1000 active input shorting out...
 

I bought this a few weeks ago from TB and have used it at reheasal without issue. Now tonight I plugged into the Active input and it starts shorting out. I tried 3 different instrument cables and still the same issue, so not the cable. I can get it to work and the passive input has no issues. I searched the posts and haven't seen anything on this, so if anyone can help I would appreciate it. I won't be able to open it up until this weekend. So hopefully just a bad solder connection since the plug itself is not loose or moving.

Thanks!!

It will be solder joints on the jack.

Thanks Steve. I hope so, this amp sounds amazing.
