Ok guys. I have a very serious question here. Backstory: My bands over the years have played alot of Mardi Gras Balls and parties...but this is the first year we have been hired to actually ride a float and play in a parade. That means a generator for electrical power. The idea absolutely horrifies me to think about. What are any ideas for safely plugging one of my Marshalls into what is an inherently transient rich and unstable voltage source?
