Hi guys!There is no Peavey tech support in my country, so I ask you to help me here.A whistle appeared in my amplifier on all channels, on a clean channel it appears when the volume knob is output to 9 somewhere, on the crunch channel it starts to whistle if the gain knob is turned above 6, on the ultra channel if the knob is turned above 4.I think most likely this is a problem with the ground, the so-called positive feedback the connection arises.Could you explain step by step where to find the problem?and another such moment:when you turn the noise gate knob on a clear channel, the noise increases, but the yellow and red channels are not affected no way, although in theory there should be a turnover.Sincerely, Tony! I use a translator, so I'm sorry for the inaccuracies if that.
