So long story.
I have an ampeg ba-115 combo. Never liked the thing just constant problems. I have had owned 3 different basses and all played through that amp. With all those basses the battery running the electronics would only last a month or two and start buzzing so I usually just put it over to passive plug in so it would stop cause I didn't want to go buy batteries every month. And yes I do unplug my basses when im done with them. So anyways, my most resent purchase as a fender american jazz bass with EMG active pickups and pre amp. I bought this bass from by best friend and we jammed a bunch with it through a markbass stack and a old ampeg stack and never had a problem. I bring it home plug it into my ampeg after a day I get buzzing in both passive and active ports. Strangely it stopped after that for a while but would buzz randomly at times. Today thought 1 month after I bought it and a brand new battery the bass is distorting in the active port but not the passive. So the battery is dying. So after that long winded speech my question is, is my ampeg just dying and junk? Also It did have smoke come out of it years ago.
Sorry for the long speech but I really want this to be answered properly. Every time I think its a problem with my bass I think its a problem with my amp.
I am planning on upgrading with spring since I have never liked the tone and the buzzing but I would like to maybe fix the problem in the mean time.
