I have my original M80 combo amp with the speaker. I haven't used it for some time and was fully operational when I stored it. I just got it out and hooked it up and found that the 2 inputs don't work. Also there is no light on the overdrive and when I plug in the pedal no light on that. The power light goes on and if I plug into the power amp in with my guitar, I hear my guitar. Looks like I'm not getting power to the inputs or something. Anybody out with some ideas? Would really appreciate it
