Yes, yet another thread. Jazz bass. Entwistle Neodymium single coil pickups. CTS 250k pots, Switchcraft Jack Socket, .047uF PolyDrop cap. Very loud and powerful. Also a bit noisy. No grounding issues - touching the string or bridge and dead silence. I let go and glorious 60 cycle hum starts. Shielding can only do so much. Do you guys just live with it?
