Hello everyone, my name is bam, I have a spyder3 15. All the sudden I lost all sound. Everything seems to be running right but I don't have any sound. So out of instinct I cranked the master knob to 10, and I can just barely here anything from the speaker, and I have to put my ear next to it to hear it. Any body know what's going on with my spyder, and maybe how to fix it. I got this amp as a hand me down and I love it, and I'm pretty handy with electronics I think I can fix it if someone could point me in the right direction. Thanks
