I read somewhere that 2A -> voltage = 100volts, 473 = 47000pF or 47nF, K = +/- 10% Tolerance and J = +/- 5% Tolerance. Is this true? I'm not sure about the Voltage 2A if its really 100volts or 50volts and K & J Tolerance? Is there really a big difference with the tolerance K = +/- 10% and J = +/- 5%? especially if I use it in a sound producing device such as tone pots of a guitar? Are these polyester film or mylar? Hoping for your kind replies. Thanks in advance...

To the best of my knowledge, you are right on with all of that. I don't know what voltage 2A may represent, however. I have not seen this sort of rating on anything other than ceramic capacitors, although it could obviously be used for any. For most applications, the exact dielectric really doesn't matter.

For the tone control of a guitar amp, the +/-10% tolerance is fine. -- unless it's part of a graphic equalizer, then tolerance is important. For just "bass", "mid-range", and "treble", +/-10% is OK.
I can't tell whether it is poly or mylar by the part number.
Either poly or mylar would be good to use in the tone control of an amp.
