Carbon Copy Delay Not Working

[joelorigo]

I have a carbon copy that I haven't used in years. Last I remember it was working but now it lets signal pass through but doesn't add any delay effect when activated. Help?

The carbon copy is a pretty complicated circuit, this might be a tough one to troubleshoot. Can you post some pics of the board, front and back?

If it's an older one they did have problems which you can get repaired but as @twebb6778 says not that easy to do here's a couple of links to see if yours is suffering the same problem

I'd contact MXR to see if they're still repairing/ upgrading them, worth a shot they're pretty good at answering
