Is there some typical amount of input impedance that your average passive pickups work best with? This is part of setting up my http://www.talkbass.com/forum/f36/experimental-fully-modular-bass-rig-902681/ ... I'll be adding a Squier Vintage Modified Jazz bass to the works in a day or so (as soon as I generate some cash-hish to finish paying off the lay away on it). I've been using an active Cort A4 up to this point. Using the passive Jazz made me think about input impedance levels and if I need to add a DI or something (a mic pre?) to place the proper load on those passive electronics that Jazz has. I'll be modifying the wiring, so that the pickups are given their own outputs straight from the volume controls (no tone control). So each pickup will have it's own channel in my modular preamp. Should I concern myself with using some sortof pickup loading circuit, like a DI on each pickup? Keeping in mind the way I'm setting this up. This experimental rig is part of a research and development effort. But it's also the way I want to use my bass. Yea, I know I'm a total square wheel. Thanks.
