I also knew it was true to a certain extent, but I was astounded when I heard the proof. Last night my band played on a local radio station, and we were given a CD of the performance when it was over. I was listening to it in the car on the way home and was struck by how different my guitar tone is to an audience than how I am perceiving it in the room/on stage. The biggest discrepancies are how dirty and how thick it seems to me vs. how it ended up on air. I keep on clean boost as an "always on", and when using humbuckers (as I mostly have been as of late) it sounds to me as though there's just a tiny bit of grit if I hit hard enough, and the sound is generally even a little thicker than I'd prefer. I often even hear things getting more gritty than I'd like and start taming it a bit. The recording reflected a dead clean, slightly thinner than I'd prefer sound. Asking my band mates confirmed that the recording is more accurate than my perception. So I guess I switch to an honest to goodness OD for my "always on." I'm not sure how to learn how to trust that my sound is cleaner to the audience than it is to me. That seems like a weird adjustment.
