This is copy/paste of what I sent to Avatar via e-mail. Just thought I'd ask for some advice from the lovely TalkBass folks as well! I purchased a B410 NEO back in 2006. It's been a great piece of equipment for the most part, but I have had a couple issues with it. The first time, one of the electronic pieces on the input panel melted back in 2008 or 9, I think. I ordered a new one from Avatar and put it in. Worked like it was brand new. Then, a few years later, the cab went out again. This time, nothing on the input panel appears to be damaged, but it puts out little to almost no volume and the sound it does make is fuzzed out and weak. Any idea what this could be? I use a Gallien-Kruger 1001RB solid state amplifer (700W + 50W for a tweeter. I can't imagine I blew all four speakers considering I never pushed the volume passed halfway (for fear of doing such a thing). Any advice or help would be greatly appreciated. A few years later, I've got some time to try and solve this problem and I'd love to get this baby up and running again. If I can avoid taking it to an amp/speaker shop, I'd prefer that.
