I just got a new Petrucci and when I plug in to the piezo and pickups my amp buzzes alot on the high gain channel and I was wonder how to stop this problem.
Man I tried it and that really worked GREAT! WOW! That's fantastic!
I noticed the same thing with my Piezo Silo the other day. My Amp and my PA are both powered by the same power conditioner. Also, it gets worse when I get closer to the mixer or computer monitor.
