First, make sure it's not the amp or cable. Turn the amp on with nothing plugged in and see if it hums. If it does, get thee to a tech. To check the cable, plug it into the amp (after the amp alone test) and listen for hum. If you swing the cable around and pick up intermitent radio stations or hum, it's enviromental and you need a shielding cage for your amp or to learn to just live with the hum.
If all those tests check out, check the wiring in the bass. If there aren't any bare, crossed or superfluously long wires, that's not the problem, and it's likely a shielding issue.
To shield the cavity you can use many things, the cheapest being double side tape and aluminum foil, the most expensive being copper faced tape. I prefer shielding paint to the tape or foil approach, becase foil tears too easily and the tape is just too much of a pain. Applying the paint is like, well, applying paint. A severely impaired monkey could do it without instruction.
Oh, and if you're using jazz style pickups, live with the hum. Some hum is unavoidable with them. Also, things like TV's, computers and lighting fixtures can cause hum, so make sure they're off when you play.
