I noticed something weird last night when playing thru headphones with the G70. A very loud hum, which I don't get if I play thru my frfr speaker. I then disconnected the Line 6 transmitter cable from my guitar, used a regular instrument cable and the hum went away.Anyone experienced the same? What could it be?
I've experienced something similar with my G90 a couple times. More of a squeal than hum actually. The first time it happened I was convinced that the receiver was broken. Repeated power-cycling didn't help. Everything looked normal on the display/LEDs and the receiver was quiet until the transmitter was turned on and then started squealing. It turned out to be a badly seated power-cable on the receiver. I thought these digital units would either work fully or not at all, but obviously not so.
