Ampeg SVT-VR hum problem

[Jerrold Tiers]

i think it was more just having creative people in charge instead of soulless bean counters that caused their attitude turnaround. that and a marketplace that voted with its dollars against loud's previous approach. i don't think we pointed out anything they didn't already know, quite honestly.

Yes....

Any thing I said, at least, would have been automatically ignored in any case....... you know, disgruntled former employee..... except that I am thoroughly re-gruntled, although I am still burnt out enough on the music biz that I hardly ever pick up a guitar..... not that there is any loss to society due to that, probably the reverse....

In any case, like the in-laws said after the wedding..... Ampeg is Loud's problem now, sink or swim. I'm hoping they keep swimming, and don't hate all of us who went before them.

My SVT-VR has this same problem from the moment I got it. It's a Made in Vietnam model that I bought in probably 2009. It's a 60 cycle hum and it goes away if you plug into the Power Amp In jack on the back. The hum was the same regardless of what input channel you used.

I finally got around to taking it in for warranty service last month after playing a whisper quiet one on a rented backline. Anyway, I just called to check on it and they said they are waiting to receive a new "main board". If it doesn't fix the problem, Ampeg intends to exchange it for a new one. I tried to point them to this solution, Ampeg SVT-VR&CL ground loop hum solution but I'm guessing they didn't try it and went straight away with a PWB replacement to conserve bench time.
