    Yup!
    Unless it is tied to the jack ground lug, it doesn't count.

    Can be through the pots if they are grounded, but has to all be connected.

    Do they make metal covers for P-90s (I've seen the dog-ear ones). If they do you could put them over the top and solder a ground wire from the covers to you pots to ground the shields.

    You mention the dirty power, but make sure you have a full 3 wire outlet with ground or your going nowhere fast.

    If things are as bad as you say there is always one of these.

    A nice isolation transformer to put between you and the power company.

    Spikes, glitches and hums get eaten up in the coils of the transformer, essentially isolating you on a separate AC circuit from the mains power.

    Most have some sort of EMI filtering as well.

    All great points Notscott, thanks for taking the time! :dude:

    So I've researched the Kinman pickups and think that may be a last ditch option. Although they are pricey, if it works and that's what I have to do to be able to play my Junior then so be it.

    First I think I'm going to open up the cavity and run a ground wire from the copper shielding in the Pup cavity to the control cavity and ground those two to the bridge ground wire and see if that helps. Hope it does cause I originally spent a lot of time taping the cavities but I guess if I missed the grounding part of the taping then that might make a difference (I hope). If I can avoid replacing the P90 I would like to keep it as it's a hand wound beast from Vineham Pickups and it sounds mean and glorious at the same time! :dude:

    For the few who were wondering if I have a guitar ground wiring problem causing excess hum, I don't. It's your standard 60 cycle hum you get from a P90 with high distortion, I've watched lots of videos with P90 hum and it sounds the same. It's not unbearable and doesn't bother me too much, I think my one band mate is just being sensitive to it..

    Thanks for all the suggestions guys!

    I like the ideas of switching to the middle position if you have 2 pups. Heck you can keep one pickup at 0 and have it silent when you switch to it.

    Too many possibilities to say for sure, but... Hum does bug listeners, for good reason, so telling them to accept it makes little musical sense, IMO. I don't like noise gates, but the ISP Decimator can be set to nicely cut out this kind of noise while having little effect on the actual musical signal. For reasonable amounts of hum, it works perfectly. For hum so loud that it come close to softly played notes in strength, nothing really works. Though P90s are noisy, they should not be insanely noisy. If there are flourescent lights, bd power, other appliances nearby, etc., you may be getting more than your share of hum and noise. Good luck -- sorry for the hassle.

    Shielding should help very much. Did it to my P90 SG and it is a big improvement.

    I haven't had a chance to get around to grounding the shielding properly with a ground wire soldered to it. Hope that helps, if not I'm at a loss cause I'll have to go with a noiseless and then I'll loose the P90 Bite..

    Ok that is a very important part for the shielding to work.

    Reach over and tighten up your drummer's snares (there's a knob on the snare drum for that). Tell him they are rattling around and buzzing too much. He'll be on your side in a heartbeat, after that.

    Kinman makes great sounding noiseless P90 pickups. Only issue is the pickup routes need to be deepened slightly. I'd use them but don't want to mess with the Historic, however would do it in a heartbeat to a USA model.

    Have you heard the Kinman back to back with a regular P90? I'm trying to get as many opinions as I can about them and if I'll still get that raunchy P90 sound I love with the Kinman. I don't know if it's worth the change if I'm going to loose that grit

    The tone magick is in the hum. You bandmate would have hated Jimi Hendrix. And that speaks more on your bandmate than on you or Jimi. :yesway:

    Tell your band mate to wear big girl panties next time. Rock and Roll has hum.

    There's people who fall into the music and the hum disappears, and there's people who focus on the hum and can't appreciate the music. Surround yourself with the right people.

    The p90 hum is yet another reason I love my GM 40 with the built in noise gate. You can dial it in just perfect for even slight noises in the signal chain.

    Its simple, turn your gain down or use a noise gate.

    I haven't heard them back to back, but playing the Kinman felt right. I wasn't missing anything, if you know what I mean. Too many noiseless pickups have that sterile feel to them, and they only get you 95% of the way there as far as sound/response.
