This is more of a question related to the fundamentals of electrical currents, but I haven't found a direct answer:
I understand the use of DC power as it relates to powering opamps and other ICs, coupling/decoupling caps, and the use of those same caps to prevent DC from getting to the guitar and such. To elaborate on my question through example, if a "flat" 9V is going across the wire, it technically can't be out of phase since it doesn't have a drastic rise and fall in voltage like AC, so is that DC power only used to power components (ICs, LEDs, and the like) or is there something more simple I am missing at a fundamental level? If this question isn't clear, I can happily try and explain myself better, but I think I know what I am asking for but if I need straightened out by all means, school me.
- How does the DC Power interact with the AC signal (guitar pickups, other audio signals, etc) coming into an effect?
