Last night at band practice, my GK MB212 Neo (8 ohm) started to distort and emit a burning smell after about 40 minutes of use. My amp is a GK 700RBII with the following settings: Volume: 11 Contour: 9 Presence: 12 Treble: 9 Hi-Mid: 12 Low-Mid: 1 Bass: 1 Boost: 12 Tweeter: 9 Woofer: 10 4/5 switch: On (playing 4-string passive Danelectro) Tweeter Hi-cut: On Woofer Hi-Cut: On I was running a Boss noise gate, but no other effects. IMO, I wasn't pushing it much at all. I've had the cabinet for about 14 months, and I use it weekly for band practice and bar gigs gigs (settings stay the same, with the Volume and Woofer settings as high as 12). I've noticed a faint electronic smell coming from it occasionally, but I always thought it was just a "new cab" smell that should go away with time. Last night, it all the sudden just didn't sound right (a little distorted, burpy/farty). I shut it down at the end of the song we were playing, and it was giving off a pretty strong burning smell -- it stunk up the room pretty good. I unplugged the cab and finished band practice with my old Peavey 15 cab. No distortion or smell from the Peavey cab using the same GK amp and settings. About 18 hours later, I removed the grill and speakers and did a visual inspection. Nothing looks burnt or charred, no loose wires, and nothing looks damaged or out of place. The burnt spell from the day before is pretty much gone. I can't pinpoint where the smell was coming from. I'm not sure if something is wrong with one of the speakers, or maybe my settings are taxing the cabinet in some way?
