So, I rolled out my new lightweight rig today. A Mesa Prodigy sitting on top of two custom-built 1x12" speakers. (Using those Genz-Benz Faitals that Avatar was selling a while back.) Played a Fender Performer bass, an instrument I, once again, thank you guys for calling to my attention.
It sounded righteous to my ears and to a few others who commented.
But between song four and five, there was a big noise, like an explosion. I thought the lead guitarist was fooling around. Nope, is was the Mesa.
Bought used, but still under warranty, though I'll pop the lid tonight and see if I can figure out what happened.
Thankfully, like many of you, I bring a backup amp. A wise decision. Back in action after a one minute delay.
