I just bought a Spider II HD75 and FBV Express MKI from my friend the other day. Everything was working great until yesterday. I couldn't get the tuner to work, so I went online and tried a bunch of calibration techniques. After some research I found that the tuner isn't compatible with the Spider II. Now I'm not getting any sound. When I first turn the amp on, I get sound for about 5 seconds, then it just stops. I'm not sure if I messed something up when I was calibrating it. How can I fix this?
