I don't know what the Nord Curse is, but sometimes the transformer can
vibrate in an instrument causing a hum or buzz - I'm not sure how to fix
that - maybe go in and tighten the screws or whatever is holding the
transformer in place. My C1 did that for a little while, but then it
stopped - no idea why.
