All basses I've looked at seem to have polypropelene caps, which are twice as expensive as ceramics (a whopping 49 cents or so  ) Is there a reason for this? |
I've never heard any knowledgeable person claim convincingly that the type of cap used made any difference at all to the sound of passive bass. I've heard a bit of hearsay, or myth-mongering, but nothing that made any sense to me.
The one reason I've heard for using polypropylene caps over ceramic in a bass that seemed plausible to me is that *supposedly* manufacturing tolerances are tighter with poly, so that if you're buying a .022 mfd cap, you have a better chance of getting a value close to .022 with poly than with ceramic.
FWIW, Chris Kinman (the Aussie guitar PU maker) claims something similar with respect to pots: he says that cheap pots can often vary wildly from their rated value (e.g., 117 kohms for what's supposed to be a 250 kohm pot).
