If you can duplicate the situation where there is no hum from the amp
when the guitar lead unplugged then you are halfway home. If the hum
occurs only when the guitar is plugged in then the problem is most
likely to do with the shield connection in the guitar cable.

Yes, I think you're right. Without the cable, there's no hum. But with
the cable it picks up 60 Hz like an antenna. Being new to the electric
guitar I guess I thought all cables were shielded to prevent hum, but I
see I'm wrong. ;-(
