Reviving this old thread to be sure I got this capacitor thing right...
The Ibanez wiring diagrams for the JS6 and JS1000 label the high pass filter capacitor wired to the volume pot as a "331" (just like Scott asked about here). Well, as Joten said, that should be a 330 pF capacitor (= .00033 microfarad). But upon checking around, I can't find any of those except by special order. Can't find them at any of the more notable guitar electronics dealers or general electronics outlets (not sure if I'm allowed to mention names here?).
What puzzles me is that DiMarzio sells a .033 microfarad capacitor, but I believe that would correspond to a 33000pf rather than to a 330pf (1,000,000 pf = 1mf). The fact that DiMarzio sell a .033mf makes me wonder if either they're labeled wrong in the wiring diagrams, or there is some labeling convention I'm not getting right.
Thanks to all you engineers out there,
