...it's not always a damn duck! Why do people on this forum continue to insist on thinking this way? They pull the whole bogus logic of "perception is reality" when in reality there's a lot more to the story than what your mere imperfect perceptions tell you. Perceptions only capture a very small part of what is happening. When you rely only on perceptions only, it makes it very easy for people who are out to screw others over to "pull the wool over your eyes". Moreover, you will never understand what is really going on when problems arise with your gear if you continue to think in this fashion. Try focusing more on what you're NOT seeing/hearing than what you ARE seeing/hearing. Lots may find that you just may get a bit farther with the whole "tone chasing" game than you are.
