I am not suffering from ear wax, but have sometimes played guitar with over-ear headphones or sometimes earbuds playing in my ears, usually news, podcasts, NPR etc. while practicing. This I am sure is not likely to improve my playing, interestingly enough, however, my playing seems a little more confident and slightly easier. I also noticed the same, though less pronounced, effect with just the headphones or earbuds and no audio program. I have not tried recording this, as I was sure that this observation was a product of my imagination.
This is strange. Are there any hearing experts that understand this weird phenomena? Is it something like the scene depicted in the "Kings Speech" where a loud recording is played to Prince Edward, while he reads aloud and miraculously does not stutter. There seems to be something interesting at work here.
Or may simply be a little nuts.
