bradh716 Posted February 8, 2010 Share Posted February 8, 2010 I have a mim p bass with spb3's installed. When I touch the poles, I get a humming sound. If I touch the pole and a string at the same time with the same finger the hum is even louder. Anyone know what this is? Link to comment Share on other sites More sharing options...
b5pilot Posted February 8, 2010 Share Posted February 8, 2010 Not sure but it sounds like a bad ground somewhere. Lydian mode? The only mode I know has the words "pie ala" in front of it. http://www.myspace.com/theeldoradosband Link to comment Share on other sites More sharing options...
kenfxj Posted February 8, 2010 Share Posted February 8, 2010 Don't touch the poles. Or is that Don't cross the streams? Push the button Frank. Link to comment Share on other sites More sharing options...
Chad Thorne Posted February 9, 2010 Share Posted February 9, 2010 Don't touch the poles. Or is that Don't cross the streams? Both good tips! Did you install the pickups yourself? If you're like me (let's hope not) you may have left something ungrounded. That's what it sounds like to me, too. Take it to a repair person or open it up to see if you can track down what's supposed to be grounded and isn't. Good luck! Link to comment Share on other sites More sharing options...
butcherNburn Posted February 9, 2010 Share Posted February 9, 2010 A lot of first timers see a grounding wire going to the bridge and think, "what the heck is this? I don't think it's even connected to anything." *snip*. If you think my playing is bad, you should hear me sing! Link to comment Share on other sites More sharing options...
Big Daddy from Motown Posted February 10, 2010 Share Posted February 10, 2010 That's fairly common with P Bass pickups, either paint the pole pieces with clear nail polish or you can just cover the pole pieces with electrical tape. Link to comment Share on other sites More sharing options...
Rocky McDougall Posted February 10, 2010 Share Posted February 10, 2010 Why do you touch the pole pieces? "Democracy is two wolves and a lamb, voting on what to eat for lunch.

J. Dan Posted February 10, 2010 Share Posted February 10, 2010 Is the hum louder or quieter if you touch the pole pieces with your tongue? If you do the above in the basement with bare feet, does it: 1) Hurt 2) knock you on your ass 3) kill you If we don't hear back, I'll assume number 3 and you're problem is essentially solved, though not in the way you preferred. Grounding. Ground wire from pickups and in some basses the bridge, should be connected to case of pots (not to mention one of the pins), as well as the sleeve of the 1/4" jack. Dan Acoustic/Electric stringed instruments ranging from 4 to 230 strings, hammered, picked, fingered, slapped, and plucked. Analog and Digital Electronic instruments, reeds, and throat/mouth.
