It had three 22nF capacitors all in all - two wired parallel to 44nF at the tone pot and a third one in the "tone switch circuit" ...
The Epiphone Rivoli Bass from 1965 had this, too!
EDIT: Maybe they made this to get less capacitor "mix errors" by unskilled workers???
The worker got three capacitors with the same value - so he could not mix the .047 and .022µF capacitor. "One here, two there" is easyier than reading the value ... | If memory serves, Gibson guitars all use .022µF caps, so it might have been more convenient to just use some of the caps of which they already had a huge supply. The idea of simplicity is very plausible as well. If only I were a Gibson factory worker in 1965...

There is no difference between two capacitors in parallel and one capacitor, in an application like this. There will be changes in leakage, ESR, ESL, etc., but these specs are not of significance to the application. The only other difference us that there is a 0.003uF difference in rating, but not only is that insignificant, but 0.044uF is within 6.5% of 0.047uF, which means that the average capacitor(s) could have an actual rating of 0.044uF or 0.047uF, or anywhere in between. |

However, allow me to say that I STRONGLY recommend a tone switch that flips between .015 ufd, off, and .047 ufd. caps. I love that. I especially like the ability to flip to bright (no cap) for say a solo and then flip back to a tone setting without having to "dial-in" any knobs. I also sometimes like the brighter tone of the .015 ufd cap, but not always. Sometimes traditional is best. Hence... |

Thanks again for all the input- I learned something here, which is a good thing ! :-) | The cap does nothing for your tone if you are not turning down the tone control. So it wont make one bass sound like another. You just have two bases that sound different... different wood, different pickups, etc.
When you turn the tone control down it will sound just like the .047µF cap. Plus, caps usually have maybe a 20% tolerance, so who knows what they are reading. You might not even get .044µF.
But it's easy enough to go to radio Shack and buy two .022µF caps and try it out.

that's how i use that bass most of the time.
I think I will just get a .047 cap and see how that sounds.
and possibly a .1 too.
Thanks!
