So I bought a BSE410H cab off some dude on craigslist about two months ago. I've been using it fairly regularly. Yesterday, I fired up the SVT3, played for about 2 minutes and then all of a sudden there was a burning smell and a plume of smoke came out of the front of the cab. Obviously, there's no sound being played out of it any longer either. There's no speakon connection in the back of the cab, so I use speaker cable to connect. Any idea what I might've done? This is my only cab so I'm pretty bummed. Thanks for any help or guidance!
