Yep,Mr. Corn fed is right.Only use a cheater if it reduces hum.This will usually be on the amp.ONLY.---No other cheaters need apply.If you get a large static shock from the carpet when touching the amp.,on a low humid.day don't do the cheater on the amp,try a different component.Your amp is telling you something,(ground me)- a tiny static is ok.
AC grounding
I've been told recently that all my gear with the exception of one needs to have a cheater plug on them. That all I need is one power cord grounded. I am not experiencing any problems, just would like it to be right. Can anybody with experience in this matter please post their input. Thanks
