The jack could be broken but this is simple to fix. The sub harmonics may be a separate problem. Dave Quote Link to comment Share on other sites More sharing options...
Hamster Posted November 8, 2007 Share Posted November 8, 2007 There's a recurring and well known fault with the power transformer on these heads - maybe it's grumbling? As for the Superfly, same quality control problems on one of the power boards. Several people on here have had problems, (me included) Hamster Quote Link to comment Share on other sites More sharing options...
Machines Posted November 8, 2007 Share Posted November 8, 2007 No loss on the sub-harmonics, but not sure about that humming problem. I can get mine to hum if I turn input/volume to max (with nothing plugged in), but that's just background interference amplified. Quote Link to comment Share on other sites More sharing options...
