    Greetings all,
    I recently aquired a guitar that has P90's in it. Are these pups always so noisy? I rewired the pots to a Gibson spec which fixed my volume/tone control issues, but still pretty noisy. I also shielded the pot cavity cover, but not the cavity itself.
    Any suggestions?
    Thanks,
    Loren

    P90s are not hum "canceling" like a humbucker is, and depending upon how much gain you're using, you'll pretty much always have some kind of noise.

    Shielding both the control and pickup cavities helps. If you do, make sure to do a thorough and tidy job of it. Also make your wiring as tidy as possible.

    This SG was a little fun project I did a while back. It now has a p90 and only ever squeals with a ridiculous amount of gain.

    In the end you will always have some hum to deal with. Its the price you pay for having the best sounding pickup in the world.

    I remember seeing a video of Joe Bonamassa talking about his tele. He said he put a piece of foam under the pickups to reduce feedback. Never tried it, but could be worth a shot.

    I just pulled the pups out and they do have foam under them, but no shielding. I have some foil tape I suppose would work.

    I won this in a raffle last April at Kauer Guitars BBQ. Played it thru my D'Lite combo a couple of weeks ago down at a local club. It was sounding pretty good. :JAM

    Better p90s hum less than bad ones.
    Braided shield wire
    Metal covers (the interference comes from the pickup more than the control cavities, especially with shielded wire)

    I kinda like the P90 hum. EVH used them on "Without You" from Van Halen III (I know, I know) and there's a moment where the rest of the band drops out aside from Eddie and you can hear this glorious VVVZZZZZZZ in between notes. But that's just me! There are plenty of noiseless P90s out there if you want to go as far as swapping pickups, if you're still getting unacceptable levels of hum after shielding. Duncan P-90 Stack STK-P1, Gibson P100, Lindy Fralin etc.

    Illitch makes a noise canceling back plate for P-90s. I have two Suhr/ Illitch BPSSC backplates on Strat-type guitars and they work very very well.

    Turn your body a little to the right :)

    P90 hum is a given, so get used to using your volume pot to stop the hum between songs.WHile you are playing, it shouldn't matter. And the tone of a good set of P90's is well worth the minor annoyance.

    Beautiful Kauer... congrats! That Kauer likely has Wolftone P90s. Very nice pickups that work for lots of players.

    Yes, hum is very dependent on where you stand in front of the amp and the angle of your body.

    I use an ISP Decimator G-String. Basically, it's a sophisticated noisegate pedal for guitar. Works well with P90s in the clubs for me.

    Loren that guitar was shielded and has Wolfetone P90's. We can talk to Wolfe about a reverse sound set so the middle is hum canceling but its about as quiet as any P90 I've played. The only other option is to move into the hum canceling versions (which I've yet to hear one that sounds as good)

    Hum is pretty much a fact of life with P90's. I agree with the poster who said you just live with it - the tradeoff being, that it is one of the best sounding pickups ever made. Braided cable, shielding etc., will help some. There are hum cancelling versions, but I've never heard one that still sounded like a P90. The Kinmans are reputedly the best, but are pricey ( I think around $150 per). Barden also makes one (also over $150 ea). Never heard either one though, so I can't comment as to how much of that P90 tone they manage to retain.

    I didn't think the purpose of the foam was about hum or feedback - I thought it like a spacer since the p90 attached directly to the wood - it also can work like a spring for raising lower pickups.

    BTW Loren, you can try pulling the covers and wrapping the bobbin in shielding tape. That might help.

    Send those crappy PU's to me and route it out for a quality humbucker.
    I'll give those POS P-90's a nice new home! No problem.
