Tone capacitor voltage rating 50 or 600 volts, difference?

[markuser]

I noticed the tone capacitors, like orange drops and paper oil Mallory cylinders, come in a wide range of voltage ratings. What is the purpose for this? Does a 600 volt make more 'tone' come through cause its bigger? My guess is the 50 volt 223mf capacitor would be more sensitive to tonalities, than the 600volt 223mf?

The sticky only tells me 600 is better than 400 for the blocking capacitor. Why, what does it sound like if DC gets through, how much DC voltage block does one need?

The ceramic disc that came on my Strat was not even 50 Volts.

Your guitar pickups produce only fractions of a volt. A 600 volt rating means it can handle that voltage without frying itself. So, any voltage rating you would ever find will be fine for guitar purposes.

The blocking capacitor is another topic entirely. It is designed to protect the guitarist against the (thankfully unlikely)possibility that a short in the amp shocks the guitarist. It needs to be that size to cover the range of possible voltages a mishap might produce.

one nice thing about lower voltage caps is their size. even orange drops come in 100v if you want em for a certain look (plus they're cheaper than their 400 or 600v counterparts). ceramic or those little green film chiclet caps work just as well
