Hey guys. I got an Ampeg SVT 3 Pro and an Ampeg SVT 610HLF recently and it sounds amazing! Well, two weeks in and I'm starting to have issues. First, the cab has started making a rumbling noise, kinda sounds like a tornado. Then the tube gain pot has become very noisy. Then this past Friday at a gig, on top of the other mentioned issues, another bassist playing it said it was cutting out and there was some crazy noise when I touched the top of the head with my fingers, until I turned off the EQ. OK, long post I know but I want to be thorough. So I called Ampeg and they said the first problem is that the SVT 3 Pro can not power the 610HLF. They said that cab REQUIRES 600 watts. He said that RMS is the required power and said I would be lucky if the speakers or drivers aren't blown. I was unaware of that and if that is the case, that means that I'm under powering my PA. Anyway, so have any of you heard of that and if so, should I upgrade the amp or downgrade to the 410HLF? Thanks guys!
