Just made a pretty catastrophic (asking to see to what extent) mistake while setting up a two amp rig. Here's what happened: I've been using an Epifani Performance 400 and Aguilar TH500 with two Aguilar DB112 cabs. While setting the rig up, I got my speakon cables mixed up and accidentally connected the speakon outputs of both amps together (w/ one of the cabs also connected to the TH). As soon as I powered everything on I realized something was very wrong and immediately powered down...but it was too late. I've tested both amps and they are both broken. The Epifani only gives me a loud hum. The Aguilar actually sounds ok until I play an aggressive note...then it distorts significantly. I can also notice a burning smell, but I can't tell what piece(s) of gear it's coming from. My question is this: What exactly happened and how screwed is the gear? Is it possible the cab that was connected is damaged also? (I don't have another amp to test it with). I'm pretty much horrified...don't even know what to do. Any help would be greatly appreciated.
