so the situation is as follows... i was practicing with a few friends when i went to do a quick pop on the 1st string. when i did this, my entire speaker cabinet lit up. again it happened and thought nothing of it, as the clipping indicator light on my swr workingpro didnt trip. when i got a closer look, it appears that the fuse or something on the crossover plate was lighting up. it looked exactly like a lightbulb. also, there was no audible distortion from the speakers. just some numbers for all you... the swr workingpro 700 puts out 450W at 8 ohms the nemesis nsp410 can handle 500W at 8 ohms i was running a boss me50b into the cabinet, and the output level on it was set at 12"oclock and i was running clean with a bit of compression when this occured. when plugged direct into the amp, this problem dissapeared. i was using a charvel csm2b with p/j setup, both pickups blended, volume all out and tone all out. its safe to say that the origin of the prob is the me50b, so my question is, is there a light in the cabinet for affect? is this a fuse or resistor of sorts? and should i be worried thanks for your replies!
