Same as the capacitors used in vintage Fender guitars and bass of 1960's and 70's.  May be used for your vintage fender guitar or a vintage guitar project. 

These do tend to run a little low and range from .034 to .43uf. 

As a reference guide:

When the tone pot is full up, the resistance of the POT has a bigger effect on your tone than the value of the cap. The value of the cap only matters as you roll the pot down:

0.1 microfarad (µf) is vintage spec. It will roll off ALL your highs and a lot of your mids leaving only bass.

0.047 -.05 µf is modern spec. It will roll off ALL your highs and a lot of your upper mids leaving only lower mids and bass.

0.022 µf is a common mod (and standard for humbuckers). It will roll off your highs leaving your mids and bass.

0.010 µf is good if you're going for Clapton "woman-tone". It only takes off the upper highs.

As with most vintage capacitors, these will exhibit current leakage at their rated voltage. In an electric guitar however, the voltage is less than 500 milli-volts (.005 volts) so these behave and function just fine in that type of very low voltage application.
