Mackie 1604-VLZ3 Premium 16-Channel Mixer
Bob Sellon - I own two Mackie mixers: the 12 channel board and a 24 track board. Though I've gotten a lot of good use out of them, I've had problems with both boards. The 12 channel board has an intermittent on one of the main outputs. It's probably just a cold solder joint but I'm really not looking forward to opening it up.
I bought the 24 track board used and it had one of the main faders missing. I'm not sure of the circumstances behind the fader amputation but it is worth noting that this can happen.
All that said, the boards are very quiet and mechanically solid.
