I'm selling my TC Electronic M5000 with two ADA cards and two DSP cards.I've had it for 8 years and it's always worked and sounded fantastic!. It has one small problem, when turning on, it says "serial information mismatch". I don't know what that means, but if you press the page button it immediately fires up and works fine. Has for eight years... I read somewhere that it might be a weak or dead battery. It's heavy, especially for a two space unit. It's built like a tank.
