Breakdown: Tom uses his killswitch. You need two pickups with seperate volume controls.
neckpick up to Zero and Bridge to Ten. When you flick the switch down it emits noise and
it stops noise. Use this like a pick in the sense that picking makes the note ring in 
same way the killswitch makes the note ring. All notes must be hammerons/pulloffs
your picking hand is using the pickup selector.
