Zemneni u Aktivnich snimacu??

Hledal sem neco jinyho ale u schematu zapojeni akivnich snimacu sem nasel tudel hlasku:

NOTE:  Do not keep your guitar’s “Ground” connected to the ground source (usually to the Trem Claw, Bridge Plate or Post, etc…). Active pickups are grounded internally, and connection to any outside sources may cause hum, buzz, or possible electric shock.
