Played an outdoor gig this past Saturday. It was 40 degrees out. My hands were so cold. We could see our breath! It went like crud. I was truly embarassed. I'll never play out in the cold again! I have to add that to the technical rider. Anyway, before the soundcheck, my amp kept cutting out on me. I'm assuming the tubes in my SVP-Pro preamp were not warm enough. I would play a few notes and all would be fine, I'd stop for a few seconds and get nothing. As the gig went on, all was well. My amp is solid state. Do you think it was the tubes in the pre?
