I use the APC Voltage Regulator on ALL my gigs to protect my equipment. My Powered mixer is more sensitive to power drops than my keyboards. The voltage regulator (UPS) keeps line voltage at a constant 120 here in the states. I find this time of the year with more outdoor gigs, power problems are more prevalent. I also keep a blue tarp in my car on outdoor gigs just in case the tent we are supplied with doesn't do the job.
