Got my feet wet working inside an amp solo today without my tech inclined friend. Grounded many points through a resistor and checked several points with a volt meter. Everything was under 1 volt dc so I jumped in.... I replaced the first coupling cap on one of my 1960’s Traynor YBA-2A amps that had the 0.1 uf value with the more standard .047 uf value. It still works so that’s good. It’s more usable now for guitar without having the bass tone pot rolled almost off. My questions is.... would changing the other 0.1 mustard caps down the line to 0.047 as well change the tone significantly more? From my reading it’s mainly the first one that changes HPFiltering?
