So, i just installed my new Seymour Duncan 1/4 pound Pbass pickups,
There is a slight, annoying hum in the back, but when i touch the strings it stops?
Also when i play with my fingers, it makes a noise, like a clicking noise almost?
How would i fix this problem?
Possibly just that the pups are hotter than you're used to, and they're just picking up the sound of your strings vibrating.

If it stops when you just touch one of the strings, it's possibly a loose wire somewhere.
Could be a grounding problem.

You are what they call a “rhythm guitarist”. While it's not as glamorous as playing lead you can still get laid. Especially if you can sing and play.

Beer is the solutions to the world's problems.

Check your grounding wire. Also are you playing near florescent lighting, a laptop/computer or a television?
