wrinkleygit Posted March 13, 2022 Share Posted March 13, 2022 (edited) Recently acquired a p-bass bitsa with a bareknuckle 58 pickup that has an annoying buzz that stops by touching the bridge or strings. First thought was no connection between bridge and ground, but checked visually and with a meter and found a good connection. Also tried the bass at home and in the rehearsal room with different amps, all with the same results, would a grounding plate beneath the pickup be of benefit or any other suggestions before I pull out what little hair I have left !!

ped Posted March 13, 2022 Share Posted March 13, 2022 Shielding. Lots of shielding. 1 Quote Link to comment Share on other sites More sharing options...
Lozz196 Posted March 13, 2022 Share Posted March 13, 2022 Yep, copper tape on the underside of the scratchplate, and in the electrics cavity. Apparently slug tape from B&Q works fine, as per another thread on here. Quote Link to comment Share on other sites More sharing options...

ezbass Posted March 14, 2022 Share Posted March 14, 2022 It’s what I use. Make sure that you have continuity between the tape and the earth loop on the bass, solder, star washer, etc. 1 Quote Link to comment Share on other sites More sharing options...

After having had 4/5 precision basses, and copper shielding most of them, I realised thanks to a technician you do not need copper shielding for a single P pickup bass! Could be grounding, connection between the split pickups, the pots making some sort of interference but I can testify this is true - a P pickup by default is hum cancelling - I can't give you a specific answer but it's what I have witnessed with my very own eyes...!

A split P pickup cancels magnetic hum but they are still susceptible to electrostatic and RF interference which will vary depending on local factors. Remember you're shielding the whole electronics not just the pickup. The wires, pots etc are all susceptible to 'hum'. My G&L SB1 was REALLY noisy before it was shielded, now it makes no noise even in front of the computer/lamp/penis enlarger 1 1 Quote Link to comment Share on other sites More sharing options...
Ander87 Posted March 15, 2022 Share Posted March 15, 2022 Oh, I stand corrected, thanks @ped ! I think after so much copper tape everywhere, the fact that I had a dead silent p bass without any noise at all, alongside that technician saying 'you dont need tape for a p bass' threw me off. 1 Quote Link to comment Share on other sites More sharing options...
NancyJohnson Posted March 15, 2022 Share Posted March 15, 2022 Maybe you have a wasp nest in there. Quote Link to comment Share on other sites More sharing options...

wrinkleygit Posted March 26, 2022 Author Share Posted March 26, 2022 Following a trip to my local B&Q, I have returned home and liberally applied the copper slugtape to all my cavities, I’m now happy to report that not only is the bass buzz free, no creatures have been harmed in the process. Thanks for the tip guys. 3 Quote Link to comment Share on other sites More sharing options...
