Hello, I have had this ampeg ba115hp for a pretty long time. Within the first few months I had it, I was playing with my bass on it, outputting to my headphones. While the amp was still on I pulled the cable out of the headphone jack, it made a pop noise. I then plugged it into the 0db input and no sound, no sound from the -15db input either. The amp will still turn on, and will still output sound from the headphone jack.
This amp is no longer under warranty since I have just had it sitting around waiting for my attention. If anyone has any clue as to what it may be please let me know. Thank you!~
