Well, I am bummed. Just brought out my SVT to its first gig since getting it back on Monday. It has been to two different techs twice now, and they both tell me it's fixed when it's not. I can't blame them, though, because they actually have been fixing things along the way. Like this time, he fixed a problem operating with the REDDI where it would make a ground noise that even adding an external pin 1 lifter to the REDDI couldn't get rid of. I needed to use the ground lifter tonight, but the hum cut down when I added it tonight, so it's not like he's jerking me around. But there is still a hum. At most settings it's kind of faint but noticeable. It's in the midrange circuit somewhere. I know this much because when I boost the mid knob or when I back off of it, it hums more. At first I thought it was just boosting mids, but it does it when you go the other way, too, starting at around 9:00 down to all the way off. It's especially bad when you set the mid selector to 200hz. And after 4 trips to two of the best techs around here, it's still not acting right, even though they tell me it's fixed. Yeah, they did fix most stuff, but this is the one thing still not fixed, and it's been driving me batty for over a year now. So I'm at a loss as what to do next. Do I keep taking it to these guys till one of them hits it? Do I risk sending an old as hell and beaten-up SVT to a serious SVT expert? Does anyone have any clue what's going on here? Why, Lord, must thou punish me so??? Oh, excuse me...sorry, just having a first world tantrum there. But I really would like this fixed. Any and all ideas are welcome.
