Not your usual issue: I swapped a P/J setup of Nordies into a Lakland JO5 w/a j-retro, and am getting funny noise. I'm getting a horrible hum off the bridge pickup when I touch only ONE of the pole pieces. I've seen others post about this issue, and it's usually a grounding problem, but I've never heard of this happening on just one of the pole pieces. It's just one particular pole that hums. Any thoughts or ideas? I've checked the grounding on this bass and it all looks good, everything zeros out on the meter. Thought it might be the pre at first, but John East (who has been unbelievably helpful and responsive) really doubted it. All help is appreciated: Pete in Tucson
