I have owned a Dirt Road Special for more than a decade and love it. It’s my secret weapon at church. However, yesterday when I went to church and turned it on, the red light came on but there was no sound. Nothing. No humming, no popping, nothing. I can get a pop when I turn it on, but there’s nothing I can do to generate sound through the input. Again, the red light comes on but there’s dead silence out of the speaker.

I really don’t want to trash this amp. Please tell me what I can do to bring it back to life. Thanks.
