Ok, I know that series/parallel has been beaten to death around here but I still can't find an answer to wether it's doable on my Bartolinis (9E active jazz pickups) or not. The installation instructions for the Barts can be found here: http://bartolini.net/instructions/pickups/active/9e/9e_active.pdf Could someone who is more skilled at electronics than me please help? If so mabe you're able to answer my second question too? I've been toying with the idea of installing a swith that turns the battery off so I can leave the cable connected to the bass without it getting drained. But somehow I've gotten the idea that it would produce a "bad" (a snap or some kind of "sparkle" sound) sound if one were to just install it so it just disconnected the battery. #1. Is this true? #2. If #1 is true would it be possible to eliminate that with a capacitor (the thought is that the power would drain out and not be just cut out)?
