I leave a back-up PA head in the car year round. It's a 20 year old Peavey which is a tank. This is just in case my mai PA dies, which it has several times over the years. This old thing has outlasted probably 8 other PA units.

The biggest problem I have with equipment is damage from inclement weather (humidity, rain, etc.) at my summer patio job. I guess it all comes with the territory.
