Re: vol & tone hot rodding 4 Active
^^ I recommend if you´re going to go about swapping cap values, buy 50 cent caps first before investing 30x as much into whjat may or may not improve anything (IMO more likely not, but I´ll get into that in a second). The large difference in cap value will have a much larger impact than a different build type.
That said, replacing a .47µF with a .022µF or a .015µF cap will massively reduce the amount of treble you can roll off using the pot. TBH if I were using values that low on actives I´d personally just leave the pot out completely.
BTW Swedish, the caps that I have here next to me from a generation 1 set of Blackouts ARE Paper-in-Oil. Are you just suggesting that he switch to what he already has, or is there method behind what appear to be infeasibly low pot values? I mean, .022 is less than 5% of .47, sounds more like a "roll the edge off" knob than a tone control to me... But if you´ve prior experience w/ such values and actives I´d love to hear it. :beerchug:
I think what would be much more helpful than people making random suggestions woud be to know what exactly you would like to hear more of, or less of, from your current setup.
