P bass hum.

I'm in the same boat - a hummy P-bass that I'd like to remedy. I rewired the bass last fall, so I think I can vouch for the wiring/grounds.

I, too, have read that if the humming goes away when you touch the bridge or strings, then the grounding is likely fine, and that you should look to shielding options next. Concur?

Don't forget the excellent shielding sticky in this forum...

I never had or heard a MIM P pup hum. No a P bass pup should not hum at all. In fact after i moved form Jazz basses to P basses the great thing besides the tone was no hum..dead quiet...check your wiring or grounds.
Does your P hum when you dont touch the strings? Is it a passive bass?

My P hums when I dont touch the strings but when touching the strings it still isnt dead quite... though noticeably better. EMG P pups that I once owned had no hum whatsoever. They're active though.

100% passive Fender P basses. One is a new MIM classic 50's reissue with US pups the other a 03 MIM P with 62 reisssue US pups with no hands on strings dead quiet...hands on only noise is when i play em :D Jazz basses are known for noise with the 60 second cycle hum etc. P basses are hum bucking and should be quiet.
 
well, I looked in my bass, and I could find nothing wrong with it. They did cut cost's with the wireing though. For example, instead of using wires on the ground wires that tuch the pots, they used 2 little copper sticks instead. They also pried the pot lugs back to tuch the pots instead of wireing it. It also uses wire with cloth around it instead of plastic. Any ideas:confused:
 
I think the best thing to do is order a pre-wired circuit from stew mac and a roll of sheilding tape. Shield that cavity well and you should only have to make three soldering connections one from the bridge ground and the two pickup wires. I find that the more stuff is done from the 'factory' the less chance I have messed it up.

Either that or bring it in to a professional and let them do it and get a money back guarantee if it still hums.

That's pretty normal wiring. Alot of companys bend pot lugs back and ad solid wire insted of stranded wire to jump as grounds....this is more solid than stranded wire. Cloth covered wire is what has been used for years in vintage basses and guitars (Fenders etc).Alot of people prefer it and swap out reg plastic covered wire for it.
