C9 and C10,What should I use?

[goat]

Mouser sent me the wrong part for C9 and C10.
To save time I am getting these from Radio Shack up the street.
.01 uF for C9 and C10 on trem head.
Which can I use or shall I say should I use?

2kVDC ceramic disc cap

500WVDC cap
or
400WVDC metalized-film cap

[goat]

All three kinds are .01uF,
I`m just wondering which are recommended?
