My music studio setup runs a SurgeX 1115 surge protector and a SurgeX UPS. These things are rated to take 10000 volt hits repeatedly and regulate the power. My house on Sunday, here in northern California where it's going through the worst storm we've seen in over a decade, we had trees fall on the power line right at the house and the transformer exploded. Thankfully, I only lost my MOTU MkIII (the only thing I stupidly didn't have plugged into the SurgeX). After a day of power outage, I came home and immediately ran over to my Mesa M9 Carbine, plugged directly into the wall. The thing with bass amps is you don't want to run them through power conditioners that limit the amount of draw on a single connection. I'm also not a fan of using something that doesn't have isolated grounds. I only need two or three sockets, but it has to screw into a Gator flight case. Do you guys have any suggestions on lightweight surge protection solutions for when you take your bigger equipment around on gigs (eg. not your D-Class, but your heavier stuff that goes in cases)?
