So I am learning the fundamentals of electrical properties and how to manipulate audio signal slowly, but I need some reinforcement especially on some of the finer details. I've got some mods in mind and I am just hoping to clear up some things prior to. The mod is to my trusty SD-1 pedal. I want to increase the pedal's low end response, so I should increase the value of certain capacitors, but which ones? Only the ceramic disc caps, or including the electrolytic as well? Only ones placed in series? Only ones placed in parallel? All of them? Could changing the value of a capacitor damage anything assuming that I solder it correctly and it is placed in the correct orientation if it is polar? I am just wondering if there are certain ones that you don't want to touch.
