On my Streamer, my pickups are buzzing when the lights are on at the church where I play and at the studio where I play they have to turn certain lights off when I play the Streamer. It has active MEC soapbars and MEC preamp. My bass guy says it's shielded properly and he even put an extra ground on per the Warwick tech's advice. I'm wondering if the MEC pickups are noisy... Particularly since my Lakland and Mike Lull basses make no such noise with Bartolini preamps and Lindy Fralin pu's.
