Have had this happen a few times now with 2 different pedals, I'll stomp one on and the amp goes into protect mode. What could be the cause of this? I run the Carvin BX500 at 2ohms into an Avatar SB12 and a Peavey 210. I don't think 2 ohms is the issue as it happened once at 4 ohms. My pedal chain is: tuner > bass big muff > VT Bass I use batteries. It has also happened with a compression pedal. Is this a symptom of a pedal problem? amp problem? cords maybe? Any hints are appreciated.
