So I was playing my 4x10 XLT and my drummer notices an orange light, that looks like it could come from a spark, appearing and disappearing very quickly from behind my speakers while I was playing. It was coming from behind the top left speaker and looked like a fireworks show behind the speakers. I called the store I bought it from, and they told me to cut the horn a bit. They said it is some sort of clipping light for the higher frequencies. Has anyone ever heard of this, or have this in the cab? First time I have ever heard of this. P.S. It was big relief to hear this. I thought there was a wiring issue with the cab.
