that's a good question.
"Any two capacitors, no matter the construction will function exactly the same. Doesn't matter if it's a ceramic disc or pio...if they are both 22 micro farads they will sound identical.
You think electrons care?"
That myth has been "BUSTED"
Two ways.I'm one who has been happy with the PIO caps I installed in a couple of my guitars, and then I read something that gave me pause. The current flowing through the cap is going to ground, i.e., it's no longer in the signal chain. If so, CAN the cap really affect tone? And if so, how?
