So just look at DC and forget about ac when looking at polarity off caps?
Resistror in series: that won't really change the impedance (mismatch), I think. isnt r70 2.2K more responsible for that?
I had a 1k in series, but choose to keep it out, for mor interesting sound options :P
I build loads of guitar fx pedals, thats why I make these choices. 8)
