Can dusty pickups produce noise?

[DivXovore]

Hi there, guys.

A straight question: can the dust collected in the pickup cavities produce undesirable noises? (such as the well known humming noise you get when not touching any metallic part, which increases with the tone pot rolled up)

Thank you

PS.: The bass in question is a passive one with P/J configuration, Volume/blend/tone knobs, with no pickguard.

No. It sounds more like a grounding, shielding or single coil bridge pickup problem. Try it with the bridge pickup turned down and the P on full. That'll give you more of an idea what it is by eliminating the single coil bridge pickup problem
