i got yesterday my GK backline 600 amp head and it works perfectly , almost

i have been playing but sometimes the overdrive turns on on his own and its like its malfuctioning but its that is alternating between channel a and b(overdrive) and it sounds like both.

im sure that the channel b button is not turned on

my first idea of a solution was that i had it in the wrong output of the head, but i switched it and is still did it..
so i have no idea of what is happening

i could really use some help

thnx

What cab are you using with it?

It might be faulty wiring. If so, it will have been the first case of Backline reliablity issues that i've heard of.

actually, utbdan had issues with his GK backline too i think.

the only thing i can think of is the footswitch, so im not very helpful there. ask the person u bought it from.

I have a Backline 600 as my primary head right now (it's my first and only one ), and I can't think of a thing that would cause it to do that. Try the footswitch if you have one plugged in to it.
