Alright, I owned a Gibson Nikki Sixx Blackbird way back in the day, returned it a few days after buying it because I didn't hear a difference in tone from my SR400. Low and behold, it was all my amp's fault and now these basses are pretty hard to find Anyway, to the point, I loved the simplistic control of an on-off switch. I have a P-bass with active EMG and a volume and a tone knob. I was wondering if I installed a killswitch if I would hear that horrid pop. I figure I won't because the pickups are active, not like my Stingray with passive pickups and active preamp. Anyway, with my thinking, I would use a SPST (On/On) Toggle switch, and basically just splice it into the middle of my battery lead to open the circuit when the switch is in the off position. Will this work? Will I get a horrid pop? Any better suggestions?
